In the future, instead of needing matlab to convert the stk file to a usable ephemeris, we wanted to start using the ephermis files that are updated by the FOT. These are announced via the acisdude email account and usually have the subject line "New ephemeris and orbitevent products". The current software expects the STK file to be in 5 minute intervals and will crash if the times are off. The interpolation of the times will fail.
