NASA uses EMR as the term for Earth Moon Rotating Frame
although I have also seen it as EMBR Earth Moon Barycenter Rotating
For conversion of EMR units to m/sec and km and seconds
I'm using the following information:
27.3217 days per lunar sidereal revolution
1 EMR_time is 27.3217/2pi = 4.348384 days
1 EMR_time = 375700.344 seconds
1 EMR distance =384400 km
1 EMR velocity = 1022 m/sec (Lunar rotational velocity)
Note: when converting EMR states to Kepler states for Lunar orbits:
The X coordinate needs to be subtracted by (1-mu) the X location of moon.

EMR_mu = .012153619
so, X_km = ( X_EMR - (1 - .012153619)) * 384400
