1) define the name of the columns
2) implement the new columns in fitsGen, which means adding them to
the template FT2 file:
https://github.com/fermi-lat/fitsGen/blob/master/data/ft2.tpl
If things have been implemented as they should, no change to the
actual code should be necessary
3) change the ft2 code to get the velocities from the magic7 and save
them in the new columns
4) tests everything end-to-end with a sample of ft2 files (by this I
mean the pulsar software)
5) release a new GlastRelease
6) reprocess the FT2 files and ingest them in the data catalog and the
public server
7) instruct L1 to use the new GlastRelease
a) Get approval for change from the CCB
b) Update FFD, ICD
c) Remove old FT2 from public server and re-ingest new files
