SLA_DTF2R - Hour,Min,Sec to Radians +   +

+
+
ACTION: +
Convert hours, minutes, seconds to radians (double precision). +
CALL: +
CALL sla_DTF2R (IHOUR, IMIN, SEC, RAD, J) +

+

+
GIVEN: +
+
+ + + + + + + + + + + + + +
IHOURIhours
IMINIminutes
SECDseconds
+

+
RETURNED: +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + +
RADDangle in radians
JIstatus:
0 = OK
1 = IHOUR outside range 0-23
2 = IMIN outside range 0-59
3 = SEC 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. +
