From the LEDA database we extracted galaxies having coordinates less accurate than 10 arcsec and having a known apparent diameter. The procedure described in Sect. 2 was applied. Sometimes, the galaxy could not be identified in a secure manner, either because several objects were in the field or because of the absence of a visible galaxy. This last case was explained by a discrepancy larger than 3 arcmin or by a poor quality of the image which made the identification difficult. Nevertheless, the identification of the galaxy was made easier by sorting them according to decreasing diameters: the right galaxy has nearly the same diameter as the previous one. Further, we were guided by the axis ratio and position angle extracted from LEDA. The skipped galaxies will be analyzed later in a more detailed manner (larger field and measurement of all galaxies in the field). Finally, 6771 galaxies were measured. In addition, another sample of 9322 galaxies was measured with a similar method with the purpose of checking the master list of galaxies indexed in HYPERCAT. When coordinates come from both sources (L and H) a simple mean can be used because both methods are assumed to have the same weight.

In Table 2 we present the final list of 17615 accurate coordinates for 17298 galaxies. The sources are the following: 1522 galaxies come from our control sample, 6771 galaxies come from the LEDA index and 9322 from HYPERCAT. 317 galaxies are in common between the two lists. The following data are given:
Column 1: PGC number according to LEDA.
Column 2: Alternate name according to LEDA (Paturel et al. 1989).
Column 3: 2000-RA and DEC. from the present paper.
Column 4: label L for galaxies from LEDA, H for HYPERCAT.

After having loaded these coordinates, 162702 galaxies have accurate coordinates in our LEDA database among the 184431 ones (i.e. 88%). Another campaign of measurement will be needed.
