[teqc] Single avg position (cart or geo) as output?

Lou (et al.)--

Now I see that in addition to the +ap flag there are also some +eep
("every epoch position") flags. Used in various combinations, +pos, +ap,
and +eep yield a variety of positions, while +eepx and +eepg seem to be
meant to be used alone to generate lists of epochs with positions.

(See attached)

Any comments on the different results or recommendation of a flags to
generate a maximally accurate position to use as initial input for
processing?
