      Description

      I have reviewed CCD defects set in the current
      obs_subaru, and updated them.
      The compiled defectRegistry and relevant files are uploaded as:

      https://www.adc.nao.ac.jp/people/~furusawa/hsc/s18a/defects/defects_20171228.tar.gz

      • Here, I tried to mask edge pixels of each CCD as we discussed in the
        telecon (see the attached figure; red boxes are edge masks),
      • and also masked out bad pixel clusters more carefully.
      • I took a conservative choice for bad amps, in the same
        manner as before, e.g., ccd=0 ch=0, ccd=43 cch=4, where I applied
        masks for the entire amp, without too much tuning up the masked areas
        and period.
      • Similarly, I have masked ccd=94 ch=2 for all periods, as this amp
        shows flat field error due to poor linearity correction with low-count
        levels.

      I am esting singleFrameDriver through coadding with these masks
      over the RC dataset, and will report you when I found something bad.
      But, in the meantime, I would be grateful if you could be prepared to
      update the defects for the next release cutout.
