From project U/04A/156: S. Leggett et al. Typical Flat and ArcFlat field frame with an obvious and small gradient across the field  A raw arc frame with a few noticable bad pixels  A wavelength calibrated, by estimation (.wce), arc frame 
Spectral FramesStandard star single bias subtracted (.sbf) image frame  Standard star composite of multiple frames.  Raw target frame of a faint source.  Reduced and wavelength calibrated target star composite frame.  Wavelength estimated spectrum of the target source.  LAF, 2005-07-28 |
