Purpose:
To change GRS mode back to mapping, to drop the Outer Stage temperature from
-83C to -98C in 5 degree steps with 1 hour between steps, wait 2 hours and
change the OS_A and GPA_TEMP collections to 5 seconds on CEB Timer 1 and
change GPA_TEMP oor counts to 0, wait four hours and tighten the GPA
temperature control band to 1 dn at -30C, wait four hours and change the MR
temperature control band from -90C to -30C, and ultimately perform a nominal
dump 41A. In addition to the temperature changes and the nominal dump, we also
Expected result:
The GRS mode will be set to mapping.  The OS_TEMP_A thermostatic control
setpoints will be set to -88C, then after 1 hour delay set to -93C, then after
1 hour delay set to -98C.  After a 2 hour delay, CEB_OS_TEMP_A and
GAMMA_GPA_TEMP will be set to CEB Timer 1 collection at a 5 second interval;
the GAMMA_GPA_TEMP out of range counts will be set to 0.  After a 4 hour
delay, the GPA temperature control band will be tightened to 1 dn at -30C. 
After a four hour delay, the CEB_MR_TEMP_A control setpoints will be changed
from -89C and -90C to -29C and -30C.  Ultimately, a nominal 41A dump will be
Why it is needed:
In order to: 1) return to mapping mode after boom deploy, 2) enable the Inner
Stage to get as cold as possible for best possible detector resolution, 3)
enhance the detector resolution as much as possible by tightening both the OS
and GPA control laws, 4) contribute more heat to the GPA from the MR so that
we may better control the GPA with the smallest heater possible (GPA 3), and
5) verify the contents of sequence 1B to know that the commands for safemode
