1 Introduction

When viewed very near edge-on, a subset of spiral disk galaxies is seen to exhibit highly flattened stellar disks with large disk axial ratios and little or no bulge component. These objects can be described as examples of pure disk galaxies.

Some of the most striking examples of pure disk galaxies are the so-called "superthin'' spirals (see Vorontsov-Vel'yaminov 1967; Goad & Roberts 1981; Matthews et al. 1999). Superthins are so named because they exhibit extraordinarily small stellar scale heights ( $h_{z}\lesssim 200$ pc; Matthews et al. 2000a,b) and no trace of a bulge, implying their disks are extremely dynamically cold. The superthins are of particular interest in studies of disk evolution, since they appear to be among the least evolved nearby galaxies both dynamically and in a star-formation sense (Goad & Roberts 1981; Bergvall & Rönnback 1995; Matthews et al. 1999). Superthins can thus serve as important laboratories for exploring aspects of the early stages of disk evolution right within the local universe (e.g., Matthews et al. 2000b). These galaxies can also be used for gauging the effects of environment on disk thickness and morphology (cf., Odewahn 1994; Reshetnikov & Combes 1997), on disk surface brightness (cf., Bothun et al. 1993), and on bulge formation (cf., Sofue & Habe 1992).

Not surprisingly, the majority of pure disk galaxies are of very late Hubble types, the largest fraction being classified as Sc-Sd (Karachentsev et al. 1993). However, not all late-type, pure disk systems are "superthin''. For example, some Magellanic spirals may have intrinsically thicker disks of somewhat larger scale height, yet still lack a bulge component and appear rather flattened when viewed near edge-on. Examples include the nearby Sdm galaxies UGC 4704 (a/b=10) and UGC 5245 (a/b=8). Interestingly, superthin and Magellanic spirals, as well as other varieties of extreme late-type spirals may often be virtually indistinguishable in terms of many of their global physical properties (e.g., luminosity, rotational velocity, ${\cal M}_{{\rm H\hspace{0.04 em}\scriptscriptstyle I}}$, $\frac{{\cal M}_{\rm HI}}{L_{\rm B}}$) and in terms of their rotation curve shapes (e.g., Goad & Roberts 1981; Matthews 1998). The origin of this morphological diversity in an otherwise similar physical parameters space remains unclear, although environment (e.g., Odewahn 1994) and dark matter halo properties (e.g., Levine & Sparke 1998) likely play key roles.

Studies of a variety of types of pure disk galaxies are of considerable interest from a galaxy evolution perspective, since these objects can help to shed insight into the question of what forms first, the bulge (e.g., Andredakis 1998) or the disk of a galaxy (e.g., Courteau et al. 1996). Dynamically speaking, pure disks are simpler systems than bulge-dominated galaxies, hence they can also be used to explore the complex problems of how angular momentum is transported in disks over time (e.g., Lin & Pringle 1987) and how galaxy disks are dynamically heated (e.g., Lacey 1991 and references therein).

For investigating a variety of questions related to galaxy disk evolution and dynamics, there are a number of advantages to studying galaxies oriented nearly edge-on. For example, only in edge-on galaxies may the vertical structure and scale height of the disk be directly probed. Vertical color gradients measured in highly inclined disks can also be used as a tracer of dynamical heating processes (e.g., Just et al. 1996), and an edge-on orientation can permit the derivation of unique constraints on the shape and mass of dark matter halos (e.g., Olling 1996).

Edge-on, pure disk spirals are not only interesting as individual objects. Fesenko (1982) and Karachentsev (1989) were among the first to recognize that statistical studies of such objects could provide a powerful means of addressing important problems in galaxy evolution and cosmology. A principle advantage of such galaxies is that they are readily and reliably classifiable over a wide range of distances. In addition, their rotation axes, inclinations, and angular diameters can be determined far more accurately than for spirals at smaller inclinations (Fesenko 1982; Karachentsev 1989).

Karachentsev (1989) has established that in most cases, distances to edge-on, highly flattened galaxies may be reliably determined using either the Tully-Fisher relation or linear size-linewidth correlations (see also Karachentsev 1991; Karachentsev et al. 1995; Kudrya et al. 1997b). Moreover, the thinnest edge-on spirals generally appear to reside outside of dense groups and clusters (e.g., Karachentsev 1999). Therefore, as noted by Karachentsev (1989), they should also typically be free of tidally-induced distortions or asymmetries that can cause scatter in such relations (cf., Franx & de Zeeuw 1992). Reshetnikov & Combes (1998, 1999) have also shown that samples of edge-on pure disks are ideal for statistically studying the origin and frequency of galactic warps. For all of these reasons, samples of flat, edge-on, pure disk galaxies can provide an excellent means of exploring issues ranging from large-scale galaxy flows, the clustering of late-type disks, to anisotropy in galaxy orientations, the formation processes for galaxy disks, the influence of environment on disk properties, and the Tully-Fisher relation and its dependence on environment and luminosity.

With goals such as these in mind, in 1993, Karachentsev et al. published the "Flat Galaxy Catalogue'' (hereafter the FGC). This catalogue was compiled through the visual inspection of photographic survey plates covering the entire sky. In total, it contains 4455 edge-on spiral galaxies with $D_{25}\ge$ $0\hbox{$.\mkern-4mu^\prime$ }6$ and apparent axial ratios $a/b\ge7$. Approximately 56% of the galaxies were previously uncatalogued (Karachentsev et al. 1994). A new, improved version of this catalogue (the Revised Flat Galaxy Catalogue) has also recently been published by Karachentsev et al. (1999).

As of 1997, published redshifts existed for only about 20% of the FGC galaxies (Kudrya et al. 1997a), and H I fluxes and linewidths for even fewer. However, such data are a crucial part of fulfilling the types of scientific goals outlined above. To help remedy this situation, Giovanelli et al. (1997) published H I parameters for 744 of the FGC galaxies, obtained primarily with the Arecibo Telescope.

Figure 1: North-South extent of the Nançay telescope beam (FWHP), in arcminutes, as a function of declination, in degrees. Diamonds show data points measured by E. Gérard (1998, private communication), and the dashed line is an interpolation between the measured points

Although the Giovanelli et al. (1997) database has already proven to be valuable for a variety of investigations (e.g., Karachentsev et al. 1995, 1999; Impey et al. 1999), obtaining redshifts for a significant sample of FGC objects outside the Arecibo declination limits is necessary for more accurately mapping the amplitude and direction of the bulk motion of galaxies with respect to the cosmic flow (e.g., Makarov et al. 1997a,b). In addition, because of the deeper limiting magnitudes of the southern sky plate material used by Karachentsev et al. (1993), the Arecibo sample is expected to be somewhat underrepresented in lower surface brightness objects. Finally, because of the local galaxy distribution in the northern hemisphere (e.g., the presence of the Virgo cluster), a sample covering the Arecibo declination zone is likely to contain fewer examples of new pure disk systems within the Local Supercluster than samples that include southern declinations (see e.g., Matthews & Gallagher 1997). For these reasons, we have used the Nançay Radio Telescope and the Green Bank 140-Foot Telescope to undertake a complementary H I survey of highly inclined, highly flattened pure disk galaxies over the declination range $-44.5^{\circ}\le\delta\le 90^{\circ}$.
