Instructions for Creating Bad Pixel Masks

This page contains instructions on how to create bad pixel masks for the WFI at the 2p2

Instructions

  • Every 3 months take:
    • 5 bias frames
    • 5 V domeflats at 20000 counts
    • 5 V domeflats at 5000 counts
  • ftp these images across to w2p2drl

  • create 3 lists in this same directory:
    • biaslist contains the filenames of all the bias frames
    • flathighlist contains the filenames of domeflats at 20000 counts
    • flatlowlist contains the filenames of domeflats at 5000 counts

  • Run the script mkBADPIX.pl :
    ./mkBADPIX.pl biaslist flatlowlist flathighlist tarfile

    • Where:
    - tarfile is the root that you want your webfile to be called (e.g. June2002)

  • This will output a file called tarfile.tar.gz which contains the 8 badpix files
