SUBROUTINE slDAFR (IDEG, IAMIN, ASEC, RAD, J)
*+
* - - - - - -
* D A F R
* - - - - - -
*
* Convert degrees, arcminutes, arcseconds to radians
* (double precision)
*
* Given:
* IDEG int degrees
* IAMIN int arcminutes
* ASEC dp arcseconds
*
* Returned:
* RAD dp angle in radians
* J int status: 0 = OK
* 1 = IDEG outside range 0-359
* 2 = IAMIN outside range 0-59
* 3 = ASEC outside range 0-59.999...
*
* Notes:
* 1) The result is computed even if any of the range checks
* fail.
* 2) The sign must be dealt with outside this routine.
