There were no differences between the commands in the STF and the ATS
files. ENA and SFTP site files are identical.
Command sequences and timings are verified. The orbit times for apogee,
perigee, 14 and 15 Re match what Ibex_orbit produces.
Please see the attached IBEX-Command-Approval-Checklist-Rev14-263-MSQ.doc.
The sun off-pointing values for Orbit 263 are as follows:
