> Please note the following:
>
>  1. I have generated (3)  separate ATS files BUS, INST and a complete
>     file. The BUS and INST will be the files to be uplinked. The
>     complete ATS, I used as a sanity check to see how the commands
>     lined up. Since we are in a new phase of ATS generation. IF you
>     have any ideas of doing this differently, let me know. 
>
>  2. The (3)  ATS files have been changed to word files and encrypted.
>     I will send out another email with the password. The files that
>     have been transferred via MFT have not been encrypted and are
>     still text files. 
>
>  3. I moved the (2)  House Keeping commands from the INST ATS to the
>     BUS ATS. I commented out the (2) commands in the INST ATS. If for
>     some reason we were unable to uplink the INST Commands for this
>     orbit, we would have been in the wrong spacecraft state for
>     executing the maneuver commands.
