Version 25 (modified by Mark Huber, 17 years ago) ( diff )

--

Initial/ongoing comparison of IPP to SuperMACHO/ESSENCE Photpipe reductions using GPC1 images from the 2009.01 release.

(don't forget to note the IPP svn-head revision # being used if different a default, say 23243?)

Test chip/skycell Sample

(because they are already made)

  • skycell.02877.31: focus on chip XY33 (~50% of field, center of camera and tent region)
     RA,Dec center = 02:23:37.250 -04:20:03.53 J2000  35.90521  -4.33431
     X,Y center (size) = 2754, 2003 (5508,4006)
     platescale = 0.2

  • skycell.02879.00: focus on chip XY22 (~90% of field, in better focus region around center. Note, large masked region in o4741g0237o.36478.ch.11951.XY22.ch.fits)
     RA,Dec center = 02:24:32.502 -05:00:06.29 J2000  36.09376  -5.00175
     X,Y center (size) = 2754, 2003 (5508,4006)
     platescale = 0.2

Warping (PSwarp and SWarp)

Check SWarp and PSWarp on the same chip to same skycell level using the following

  • pswarps - uncompressed, single FITS files in
