Block 12 - Install new PCK/TPC

Description

New planetary constants, or an update RA and DEC of Bennu pole, rotation rate, etc.

Capture state of system by running RESIDUALS and make a copy somewhere for comparison
Update INIT_LITHOS.TXT and make_sumfiles.txt with new PCK/TPC
Run MAKE_SUMFILES Option 1 to update the NOMINALS
Capture state of system by running RESIDUALS again... did the s/c move the amount you would expect?
Make sure the sigmas in NOMINALS are small so that the next step brings the SUMFILES close to the NOMIALS (if the s/c didn't move much in the previous step you can probably skip this step and the next)
GEOMETRY 20-15-n-n
Run DYNAMICS to set the sigmas to their proper value
Run GEOMETRY 20-15-n-n again
Iterate
