Get the Channel 45 scan head count and convert it to a brightness temperature using UWisc subroutine TEMBCK.F (from Liam Gumley (UWisc)) 2. Call subroutine MASCAL.F (from Liam Gumley (UWisc)) which uses the chan45 scan head temperature and the cold and warm black body counts/temperatures for computing the corrected slope and intercept for all IR bands.
