Overview

  • This version uses the column names D and D_TV03 in the dispersion tables that Stephane made on 2009 May 22. 
  • ACQ/IMAGE data can be calibrated. 
  • Background smoothing for NUV is done only over the region corresponding to the detector (i.e. no longer extending into the buffer region). 
  • Some keywords have been renamed, and there are new keywords, e.g. for the number of events and the amount of time lost due to FUV bursts and to the BADTTAB.
  • For TIME-TAG data a modified GTI table will be appended to the corrtag file that accounts for time intervals lost to FUV bursts or due to BADTTAB. 
  • For ACCUM data the input headers are used to write the flt and counts files.
  • If the user specified a text file with values to override the wavecal shifts in the dispersion direction, the name of that file will be appended to the value of the WAVECALS keyword.
