    Previous CALDB UVOT releases


  • Swift UVOT CALDB 20231208 Release Note
  • ===========================================================
     Update 2023-12-08
      
      *) bcf/senscorr/swusenscorr20041120v007.fits
    
      This file contains information about the long-term change in the
      UVOTA detector sensitivity. It extends the information 
      in swusenscorr20041120v006.fits and revises the information 
      for the W1, W2, M2, and White filters. It is used by UVOT photometry software.

  • Swift UVOT CALDB 20211108 Release Note
  •  
    =========================================================== 
     Update 2022-02-25 
         *) /bcf/flat/swusshsens20041120v001.fits 
          /bcf/flat/swusslsens20041120v001.fits
          /bcf/flat/swussmsens20041120v001.fits 
    
       New Small Scale Sensitivity (SSS) caldb files have been defined for low (conservative), mid 
       (intermediate) or high (aggressive) screening. SSS masks identify regions of 
       the detector where the sensitivity is below a certain threshold in the heat maps.
       The choice of threshold determines the number and size of the low sensitivity regions masked
       and allows depending on the science the tolerance to error in the flux measurements.
       This update is released with CALDB version 20211108 in Feb 22.

         These files contain an update for the telescope definition 
         files.The UVOT boresight for the lenticular filters has been drifting
         at about 1 arcsecond per year since early in the mission.
         Two sets of files were generated to correct this drift.
         The first with validity data starting from 20130512 and applicable to all 
         data taken from 2013-06-12 till 2016-03-18. The second with validity data 
         starting 2016-03-18 and applicable to all data taken after 2016-03-18 
         Data taken before 2013-06-12 uses previous released teldef files appropriate
         for that time period.

             The distortion map extensions in the lenticular, magnifier,
            and grism teldef files have been updated.  The new distortion
            maps have been smoothed to eliminate spurious ripples that are
            sometimes seen in UVOT SKY images.  The new teldef files will
            produce SKY images with slightly different sizes and
            astrometry when compared to images processed with the older
            teldef files.

            This file contains the bad pixel data for times starting

      *) bcf/teldef/swugen20041120v104.teldef
    
            The UVW2 filter has been removed from the general teldef file
            because it has been found to have a different plate scale from
            the other filters.  UVW2 teldef information is now in the
            swuw220041120v101.teldef and swuw220051124v101.teldef files.
            The change in the plate scale is accounted for by compressing
            the distortion map.  This was done so the output SKY images
            for UVW2 will have the same plate scale as the other filters.
    
      *) bcf/teldef/swuw220041120v101.teldef

        All files and indices delivered before May 5 2006
        can be found under uvota_pre20060505.
    
        This was replaced by a new uvota CALDB tree where only the 
        good files delivered up to 5 May 2006 were maintained. 
        This new directory tree fixes the problem with the files
        named 'rmf'  that were infact 'rsp' and includes the 
        latest response files. The 'rmf' directory has been replaced by 
        the 'rsp' directory.

        in this new directory tree.
