3. The BACKSCAL column is not preserved in output (31 Aug 2006)

Bugs

1. dmtype2split copies only the first component when splitting a vector column.

   When breaking up a vector column, e.g.:

   unix% dmtype2split 'region.fits[cols x,y]' myout.fits 
   

   dmtype2split copies only the first component of the vector:

   unix% dmlist myout.fits cols
    
   --------------------------------------------------------------------
   Columns for Table Block SPECTRUM
   --------------------------------------------------------------------
    
   ColNo Name Unit Type Range
      1 POS pixel Real8 -Inf:+Inf
   

   The POS column should be a vector, but only contains the 'X' column data.

2. dmtype2split changes the CHANTYPE header keyword (31 Aug 2006)

   If the CHANTYPE in the input file is PI, dmtype2split changes it to PHA in the output file:

   unix% dmkeypar pha2.fits CHANTYPE echo+
   PI
   
   unix% dmtype2split "pha2.fits[#row=9]" row_9.pha
   
   unix% dmkeypar row_9.pha CHANTYPE echo+
   PHA
   

   If the CHANTYPE is PHA in the input file, it is correctly propogated to the output.

3. The BACKSCAL column is not preserved in output (31 Aug 2006)

   If the input file has a BACKSCAL column (or columns), that information is not copied to the output file. Instead, the BACKSCAL value is added as a header keyword.
