window.fits

This file describes the geometry of a subsample of the large-scale structure sample in terms of spherical polygons (the concept is explained well at the mangle site). For each polygon, we give information on the flux limits and the completeness.

This file can be read in using the 

read_fits_polygons

tool in idlutils.

The columns are:

  1. XCAPS[3,N]: directions for each cap (as specified in the mangle documentation)
  2. CMCAPS[N]: size of each cap (as specified in the mangle documentation)
  3. NCAPS: number of caps
  4. WEIGHT: weight assigned to each cap (ignore this)
  5. STR: area of each cap in steradians
  6. USE_CAPS: bitmask designating which caps to use
  7. NGOT: number of classified spectra in the sector containing this polygon
  8. NTARGETS: number of targets in the sector containing this polygon
  9. FGOT: NGOT/NTARGETS
  10. DIFFRUN: 1 if the "best" photometry is from a different run than the target geometry, 0 otherwise
  11. MMIN: bright apparent magnitude limit in this polygon
  12. MMAX: faint apparent magnitude limit in this polygon
  13. SECTOR: sector this polygon is contained in
