The BeginFileThrust and EndFileThrust commands for the THF can cause issues writing an STK ephemeris file depending on the ordering of the commands.
If the STK ephemeris for a smoother is enabled before the BeginFileThrust command, the STK ephemeris does not cover the span of observations. This can be worked around by enabling the ephemeris AFTER the BeginFileThrust command.
If the STK ephemeris for a smoother is not disabled before the EndFileThrust command, the STK ephemeris is blank. This can be worked around by disabling the ephemeris BEFORE the EndFileThrust command.

It’s worth considering adding a warning to the log if the epochs are not monotonically increasing in the data sent to the ephemeris file.
