3 Galaxy photometry

3.1 Data reduction

Standard reduction procedures for CCD photometry were applied. Once raw images were bias subtracted and flat-field corrected, cosmic rays were removed. The dark current was found to be negligible for all the cameras. During each night at least 10 bias images were obtained; in all cases they were very stable, so for each run we combined all of them to get an averaged bias that we subtracted to each image. We also took at least eight dome-flats that we combined and corrected from illumination failure with a combined sky-flat of at least six images. Finally cosmic rays were removed using the CR_UTILS IRAF[*] package that replaced the values of the affected pixels by an interpolation of the surrounding pixels in an annulus. Foreground stars near the objects were also masked using a similar procedure.

3.2 Flux calibration

Integrated photometry was performed using the APPHOT IRAF package, mainly the polyphot and phot tasks. Standard Landolt ([1992]) stars observed during each night under different airmasses were used for calibration. They were measured with different apertures using the phot task. The curve of growth of each star was built following the algorithm found in Stetson ([1990]). A least-square method was used to get the following transformation equations:

\begin{displaymath}B-2.5\cdot \log(F_{B})=C+K_{B}\cdot X+
K_{B-r}\cdot (B-r) \end{displaymath} (1)

where B is the Johnson B apparent magnitude, FB is the flux in counts ${\rm s}^{-1}$, C is the instrumental constant, KB the extinction, X the airmass, and KB-r the colour constant referred to the Johnson B-Gunn r colour (we already had Gunn r magnitudes of the galaxies).

Whereas our sample of galaxies was observed in the Gunn r filter, photometric star data from Landolt ([1992]) refer to the Cousins system. Therefore, we have corrected the colours included in the Bouguer fit with an averaged $r-R_{\rm C}=0.37$ (Fukugita et al. [1995]).

The errors of the galaxy magnitudes due to the Bouguer fit were calculated for each object with the covariance matrix of the least-square fit according to the expression:

\begin{displaymath}\Delta m_{\rm Bouguer} =
t_{1\%}\cdot \sigma_{\rm lsf}\cdot
\sqrt{X^{\dagger}\cdot A^{-1}\cdot X} \end{displaymath} (2)

where $t_{1\%}$ is the value of the t distribution with $N_{\rm stars}-4$ degrees of freedom, and ${\sigma}_{\rm lsf}$ is an unbiased estimation of the standard deviation of the least-square fit. The variance-covariance matrix of the least-square fit, A, the column and line matrixes X and $X^{\dagger}$ for each object are defined as:

\begin{displaymath}A=\left[\begin{array}{ccc} N &
{\displaystyle \sum_{i=1}^{N}...
...\displaystyle\sum_{i=1}^{N} (B-r)_{i}^{2}} \end{array} \right] \end{displaymath} (3)


\begin{displaymath}X=\left(\begin{array}{c} 1 \\ X \\ B-r \end{array} \right) \h...
...er}=\left(\begin{array}{ccc} 1 & X & B-r
\end{array} \right). \end{displaymath} (4)

The transformation equations for each night are listed in Table 2.

3.3 Galaxy integrated photometry

Many galaxies were found to be very irregular in shape, being very difficult to apply the standard circular apertures. We decided to measure fluxes using the IRAF task polyphot. This task allowed us to build polygons around the galaxies including the whole object and minimizing the area of sky also included. At least two polygons were used in three different positions (securing a minimum of six measures) to avoid errors due to the specific shape of the polygon. The sky was determined as an average of at least 8 measures with a circular aperture around the object.

The errors were calculated as follows. Each flux measurement included an error due to Poisson noise, the uncertainty in the sky determination, and the readout noise of the CCD. This error, in magnitude representation, is described by the expression:

\begin{displaymath}\Delta m_{i} =
1.0857\cdot\frac{\sqrt{\frac{F}{G} +
{\rm Ar...
...c{{\rm Area}^{2}\cdot\sigma_{\rm sky}^{2}}{N_{\rm sky}}}} {F}
\end{displaymath} (5)

where F is the flux in counts s-1, G is the CCD gain in counts ${\rm e}^{-1}$, Area is the area in pixels enclosed by the polygon, $\sigma_{\rm sky}$ is the standard deviation of the sky measure and $N_{\rm sky}$ is the number of pixels of the sky measure. The first term of the sum inside the square root is the Poisson noise (square root of the number of electrons counted), the second term refers to the uncertainty in the determination of the sky level, and the third is related to the effects of flatfield errors in the sky determination. Several polygon measures were taken to assure a good magnitude determination. The final associated error was chosen to be the greatest among all the associated to each polygon and the standard deviation of all the polygon measures:


\begin{displaymath}\Delta m_{\rm Flux} \: = \: \max(\Delta m_{i}).
\end{displaymath} (6)

Finally the Bouguer line errors were also taken in consideration, yielding a final expression for the magnitude error:

\begin{displaymath}\Delta m_{B} =\sqrt{(\Delta
m_{\rm Bouguer})^{2} + (\Delta m_{\rm Flux})^{2} }.
\end{displaymath} (7)

Apparent total B magnitudes, as measured with this method, are listed in Table 3. We have also calculated the B magnitudes inside the 24 mag arcsec-2 isophote (B24), and the total magnitudes using the Kron ([1980]) radius defined as:


\begin{displaymath}r_k=\frac{\displaystyle \sum_{i}
r_i\cdot F_i}{\displaystyle \sum_{i} F_i}
\end{displaymath} (8)

where i runs from the center to the aperture which has an isophotal level corresponding to the standard deviation of the sky. A second set of total magnitudes were measured within an aperture of radius $2\cdot r_k$ applying this method. In average, Kron magnitudes were 0.02$^{\rm m}$ fainter than the polygonal ones; the absolute differences ranged from 0.00 to 0.47 magnitudes. The highest differences were always due to the presence of field stars inside the Kron aperture or flux contamination from nearby objects, which have been previously deleted interactively using the CR_UTILS IRAF package.

The apparent magnitudes were converted into absolute magnitudes using the redshifts listed in Table 1. The standard galactic extinction correction was applied using the Burstein & Heiles ([1982]) maps. Because the Balmer decrements are also available for most of the objects (Gallego et al. [1996]), we provide these values in Table 1 to allow the correction from total extinction (Galactic and internal) through the B-V colour excess.

3.4 Effective radii and colours

The effective radius (defined as the radius that contains half of the total light) in the B images was measured in two different ways. First, an equivalent half light radius in arcsec was calculated as the geometric mean of the major and minor semi-axes of the elliptical isophote containing half of the galaxy flux (i.e., $B_{\rm T}+0.75$ magnitudes); this half-light radius $r_{1/2}(\hbox{$^{\prime\prime}$ })$ is tabulated in Col. (5) of Table 3. We also measured the flux of the galaxy inside circular apertures and selected the one containing half of the light. These radii were transformed into effective radius in kpc ($R_{\rm e}$, Col. (4) of Table 3) with the formula:


\begin{displaymath}R_{\rm e}{\rm (kpc)}=58.1\cdot r_{\rm e}(\hbox{$^{\prime\prime}$ }) \cdot
\frac{[(1+z) (1+z)^{0.5}]} {(1+z)^2}\cdot \end{displaymath} (9)

B-r colours have also been calculated. We first aligned the Johnson B images with the original Gunn r images from Vitores et al. ([1996a]). Permitted modifications were rotation, scaling and shift. We measured the aperture colour inside the 24 mag arcsec-2 Johnson B isophote. Then we also obtained the colour inside the isophote of radius the effective radius (as measured in the B band). Again, the Galactic extinction correction was performed using the Burstein & Heiles ([1982]) maps. Conversion constants are 3.98 in B and 2.51 in r; both values were interpolated from Fitzpatrick ([1999]).

In Table 3 we summarize all these results: apparent total and B24 magnitudes in Cols. (2) and (3); effective radius in kpc and arcsec in Cols. (4) and (5) respectively; absolute B magnitudes corrected from Galactic extinction in Col. (6) and effective and isophote 24 mag arcsec-2 B-r colours in Cols. (7) and (8). Colour information is only available for those galaxies with Gunn r magnitude measured by Vitores et al. ([1996a]).

$^\dagger$ Total colour calculated from integrated magnitudes. No radial data are available due to low SNR in the images.

Table 3: (1) UCM name. (2) Total Johnson B magnitude calculated with several polygons. We have also measured the asymptotic magnitude at two Kron radius yielding an average difference with the polygon measure of 0.02 magnitudes. (3) Johnson B magnitude measured inside the 24 mag arcsec-2 isophote. (4) Effective radius in kpc measured in circular apertures and converted to distance using a Hubble constant H0=50 km s-1 Mpc-1 and a deceleration parameter q0=0.5. (5) Equivalent half-light radius calculated with isophotal apertures. (6) Absolute magnitude corrected from Galactic extinction according to the maps of Galactic reddening of Burstein & Heiles ([1982]). (7) B-r colour measured inside the effective isophote. (8) B-r colour measured inside the 24 mag arcsec-2 isophote.
