SLA_KBJ - Select Epoch Prefix +   +

+
+
ACTION: +
Select epoch prefix `B' or `J'. +
CALL: +
CALL sla_KBJ (JB, E, K, J) +

+

+
GIVEN: +
+
+ + + + + + + + + +
JBIsla_DBJIN prefix status: 0=none, 1=`B', 2=`J'
EDepoch - Besselian or Julian
+

+
RETURNED: +
+
+ + + + + + + + + +
KC`B' or `J'
JIstatus: 0=OK
+

+
NOTE: +
The routine is mainly intended for use in conjunction with the +sla_DBJIN routine. If the value of JB indicates that an explicit + B or J prefix was detected by sla_DBJIN, a `B' or `J' + is returned to match. If JB indicates that no explicit B or J + was supplied, the choice is made on the basis of the epoch + itself; B is assumed for E <1984, otherwise J. +
