      Description

      Ikeda-san and I noticed that defects masking for ccd=43 set in the
      hscPipe 5.0 was insufficient for recent data. Irregular counts in a
      channel of ccd43 leak into the coadd image. Please see the attached
      figure. Right panel is a resultant coadd (wide g tract=9813 patch=6,5)
      with the default hscPipe 5.0, and the left panel is the reprocessed
      data with a modified mask.

      I am sorry for my last proposal of the mask, which was incomplete, and
      to have not found this problem earlier. If possible we would like to
      update the defects for ccd=43. We suggest to mask the whole channel
      for all ccd=43 data since 2016-04-01, i.e., use the below for ccd=43
      (in 2016-04-01, 2016-11-22, and 2016-12-23):
