Preliminary Target Selection for the DESI Bright Galaxy Survey (BGS)
  The Dark Energy Spectroscopic Instrument (DESI) will execute a nearly
magnitude-limited survey of low redshift galaxies ($0.05 \leq z \leq 0.4$,
median $z \approx 0.2$). Clustering analyses of this Bright Galaxy Survey (BGS)
will yield the most precise measurements to date of baryon acoustic
oscillations and redshift-space distortions at low redshift. DESI BGS will
comprise two target classes: (i) BRIGHT ($r<19.5$~mag), and (ii) FAINT
($19.5<r<20$~mag). Here we present a summary of the star-galaxy separation, and
different photometric and geometrical masks, used in BGS to reduce the number
of spurious targets. The selection results in a total density of $\sim 800$
objects/deg$^2$ for the BRIGHT and $\sim 600$ objects/deg$^2$ for the FAINT
selections.A full characterization of the BGS selection can be found in
Ruiz-Macias et al. (2020).
