VizieR Online Data Catalog: Candidate halo dark matter (Oppenheimer+, 2001)

Photographic astrometry and photometry is presented for all objects plotted in Figure 1. The first file gives data for all sources plotted in Figure 1 (small dots) while the second file lists the subset of those objects that where followed-up for low resolution spectra on the CTIO 4m telescope, along with a spectroscopic classification indicating the nature of each source (these are plotted as coloured symbols in Figure 1). At H_R>22.5, all objects in the first list were followed up at CTIO, and 15 objects were found to be spurious (mainly at very large H_R and/or faint magnitudes - the second file gives details of which candidates are likely to be spurious. The first file also contains duplicate records in Schmidt field overlap regions - these are useful to assess the true external measurement errors on the photographic astrometry/photometry.

Detailed analysis of the white dwarf subsample from these data is presented in Oppenheimer et al. (2001Sci...292..698O) and further analysis (including photometric transformations for WDs) is presented in Salim et al. (2004ApJ...601.1075S).
