Block 12 - Install new PCK/TPC

Description

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

Procedure

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
