lines. We identified 63 blue stars of which 39 appear to be Be stars. While there is little ambiguity about the Be stars, SIMBAD labels two of the blue stars without emission lines as PNe, one as a Mira-type star and one only as a Two Micron All Sky Survey (2MASS) infrared source (@2003yCat.2246....0C). We also found eight objects that could be either blue stars or YSOs. The median OGLE-III color of these blue stars is $(V-I)\simeq0.1$ mag.

[*Red stars*]{}. These are stars with red spectra sometimes showing molecular absorption bands. We identified 68 red sources, where SIMBAD classifies 4 as infrared sources (one YSO from @2009ApJS..184..172G and three 2mass sources), 1 as a PN, 1 as a YSO, 1 as an asymptotic giant branch star, and 1 as a galaxy. The median OGLE-III color of these sources is $(V-I)\simeq1.1$ mag.

Discussion {#sec:discussion}
==========

The yield of our survey is determined by a combination of contamination and depth, where it is difficult to fully characterize the effects of depth because of the large variation in integration time created by the weather. For discussion, we simply combine the four fields (Table \[tab:selectionresults\]). We know from the surface density of candidates compared
