BADPIX masks for the
This page contains BADPIX masks for the WFI.
These BADPIX mask files contain 8 individual BADPIX files - one for each of the WFI chips.
detailed report on the creation of the BADPIX masks can be found
The following is a summary of the processes and the resulting BADPIX masks for WFI.
Image Reduction and Analysis Facility PACKAGE = ccdred TASK = ccdmask image = Input image mask = Output pixel mask (ncmed = 7) Column box size for median level calculation (nlmed = 7) Line box size for median level calculation (ncsig = 15) Column box size for sigma calculation (nlsig = 15) Line box size for sigma calculation (lsigma = 20.) Low clipping sigma (hsigma = 20.) High clipping sigma (ngood = 5) Minimum column length of good pixel seqments (linterp= 2) Mask value for line interpolation (cinterp= 3) Mask value for column interpolation (eqinter= 2) Mask value for equal interpolation (mode = ql)
