Use:	real function ircc_solid(
	detector )	I	integer

	ircc_solid	effective solid angle of the detector
	detector	detector number

Description:
       It returns the effective solid angle of a given detector
       as listed in the Explanatory Supplement to the IRAS Faint
       Source Survey, Table number II.D.1 page II-50.
       The solid angles are in steradians.
       The dead detectors have solid angle == 0.0
 
       No provisions (yet) for LRS detectors. 
       They are also == 0.0.
