/* DARKRATE is the nominal NUV dark count rate per second over the entire
   detector, gotten by summing counts in i9u1759io_drk.fits[1], excluding
   pixels flagged as bad.  This is used in NUVFactor in dodark.c.

   With this value of DARKRATE, the factor for scaling the NUV dark image
   will be one if the temperature is 35.5764 degrees C.
