ES1 SWIRE B Oct06

From NYU CCPP Wiki

This is a page about the PRIMUS project.

The ES1-SWIRE observations for October 2006 targets galaxies and QSOs detected the optical/IR imaging.

Daniel worked out how to select galaxies appropriately from this catalog, using his SWIRE target prescription (which I hope to have copied correctly). All targets used below pass the "basic cuts" and aren't a bright star. Before having the cuts applied, all SDSS filter magnitudes have had the SWIRE AB corrections applied. However, the catalogs we carry around do not have these applied; the catalogs are left alone.

These F-stars are based on B, V, R colors from SWIRE.

There are some notable differences between this field and the CDFS field:

  1. There is only one external catalog guaranteed at the faint end (the Berta catalog)
  2. When excluding bright stars, QSOs are checked for with only the IR cuts, not the optical

The priorities are:

  1. SWIRE_CALIB (107): F stars (from the optical imaging)
  2. SWIRE_BRIGHT, SWIRE_FAINT (207): Density-dependent sparse-sampled primary objects. Bright set is everything with R < 22.7. Faint set is 22.7 < R < 23.7, where IR sources and external sources are guaranteed. Other faint galaxies (with R < 23.2) are sparse sampled at 30% if collided, 100% if not.
  3. SWIRE_FILL (307): All sources not in primary sample with R < 23.2.
