IPP Data Reduction Stages

In order of processing:

• Raw
  • Straight from the telescope
• Chip
  • Images:
    • detrended
      • flattened
      • debiased
  • Products:
    • PSF measurement
    • point source catalogues
• Camera
  • Images
    • Nothing new
  • Products
    • astrometry for entire focal plane
    • some position-dependent masks
• ( Fake )
  • Images
    • detrended
• Warp
  • Images
    • Warped to predefined skycells (i.e. images in sky coordinates)
  • Products
    • Remeasured PSF
• Stack
  • Images
    • Combination of warps (images in sky coordinates) convolved to a common PSF
  • Products
    • Nothing new
• Diff
  • Images
    • Difference between two frames or a frame and a stack, all in sky coordinates (a.k.a warps)
• Magic
  • Stripes added to hide high-proper motion objects (satellites and other things which shouldn't be masked)
• Addstar Stage
  • ?
