SLA_DAF2R - Deg,Arcmin,Arcsec to Radians   

ACTION:
Convert degrees, arcminutes, arcseconds to radians (double precision).

CALL:
CALL sla_DAF2R (IDEG, IAMIN, ASEC, RAD, J)

GIVEN:

IDEG I degrees
IAMIN I arcminutes
ASEC D arcseconds

RETURNED:

RAD D angle in radians
J I status:
1 = IDEG outside range 0-359
2 = IAMIN outside range 0-59
3 = ASEC outside range 0-59.999$\cdots$

NOTES:
1.
The result is computed even if any of the range checks fail.
2.
The sign must be dealt with outside this routine.
