ash/freed   oct 1968   subroutine eclprc
Determine mean lunar orbit orientation angles and AA trans-
formation matrix from ecliptic of date to equator of reference
epoch because mean lunar orbit package was not called.
Modified Aug 1972 by R.King to calculate orbit quantities for
lunar rotation integration.

MNRT1= 0 LUNORB or ROTMAT is calling routine, determine
anomx, asc, per, and aa matrix
1 MORFN is calling routine, determine long, asc,
their time derivatives, and aa matrix
