WBSC3 & HAM4 HEPIs Locked on Stops

The ITMX and HAM4 HEPIs were locked this morning.  Attempted to lock them at the nominal isolated position but that never works perfectly.

HAM4 diffs for position are 2, 13, & 44 um for x, y, & z.  For rotations the diffs are 2, 5, & 2 urads for RX, RY, & RZ.

For the ITMX, the isolated vs locked position differences are 58, 48, & 51 um for x, y, & z.  For the rotations the differences are 15, 16, & 16 urads for RX, RY, & RZ.

Not terrible but they should be close enough such that Jim won't have a real difficult time locking the ISI and Betsy will be able to set EQ stops.
