| Summary |
The number of sources that can be used for the calibration of narrow band photometry is small compared to that of broadband photometry. Narrowband photometry of point sources is important for a variety of reasons, from the search for intracluster planetary nebulae to understanding the star-formation history of the universe (e.g., through Lyman alpha-emitting galaxies). There will be a need in the next several years for more photometric narrow-band standard stars with the next generation of surveys (e.g., with the Large Synoptic Survey Telescope,or the One-Degree Imager). Thus, more standard stars (both primary and secondary) for narrow band need to be identified and cataloged. Over the last three years, we have been collecting narrow-band [OIII] 5007 images of portions of the Virgo Cluster, along with broad-band V and R. The data were collected at the 2.3m Wyoming Infrared Observatory and the Kitt Peak 0.9m.We present our [OIII]5007 photometry calibration of point sources in the Virgo Cluster region, most of which are intracluster planetary nebula. For greater utility of this catalog, we also cross-calibrate our photometry with the Sloan Digital Sky Survey ugriz system. In addition, we take advantage of the long baseline of our observations to find time-variable sources (rejected from the standard star catalog) such as background quasars, supernovae, novae, and micro-lensing events.
