!Description:

  Integer function water_day.c
  Computes the initial clear sky confidence for daytime water pixels.
  Called from perform_cloud_tests.c

!Input arguments:
  none

  Inputs from structure variable 'pxin' of type "pixel_in" defined in
  pixel.h.

!Output arguments:
  none

  int return_code   successful completion is zero, otherwise non-zero
                    (returned through function call)
