SLA_DJCAL - MJD to Gregorian for Output +   +

+
+
ACTION: +
Modified Julian Date to Gregorian Calendar Date, expressed +in a form convenient for formatting messages (namely + rounded to a specified precision, and with the fields + stored in a single array). +

CALL: +
CALL sla_DJCAL (NDP, DJM, IYMDF, J) +

+

+
GIVEN: +
+
+ + + + + + + + + +
NDPInumber of decimal places of days in fraction
DJMDmodified Julian Date (JD-2400000.5)
+

+
RETURNED: +
+
+ + + + + + + + + +
IYMDFI(4)year, month, day, fraction in Gregorian calendar
JIstatus: nonzero = out of range
+

+
NOTES: +
+
1. +
Any date after 4701BC March 1 is accepted. +
2. +
NDP should be 4 or less to avoid overflow on machines which +use 32-bit integers. +
+

+
REFERENCE: +
The algorithm is derived from that of Hatcher, +Q.Jl.R.astr.Soc. (1984) 25, 53-55. +
