 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.
==========================================================

 
=========================================================== 
 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. 
==========================================================

 Update 2020-12-15
  
   *) /bcf/badpix/swubadpix20050105v104.fits  
  

  This update is to correct the information in the file swubadpix20050105v103.fits
  released with CALDB 20201026. The primary change in swubadpix20050105v104.fits
  is in the values of the TIME column.

     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

         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.

        a Vega spectrum.  The colour corrections convert magnitudes

        spectra (stars) and gamma-ray burst spectra.

       so that 100% of the energy in enclosed in an aperture with

       are approximate only.  They assume that there is no variation
       in the PSF with position on the frame, roll angle, or count
       rate.  They should be treated as having an uncertainty of
       approximately 10%.
