[daip] Question about LOCIT

Hi. Thanks to Eric we now have a version of LOCIT that runs
without complaint on the single-polarization from our JPL test
interferometer. However, I now have a question about interpreting
the results. The expected errors in our interferometer baselines
are several cm (possibly as large as a few tens of cm). LOCIT
produces antenna position corrections that are sub-cm, with sub-cm
uncertainties. It seems implausible that the true antenna position
correction could be so small. Is there an implicit assumption in
LOCIT that the a priori antenna positions are known to less than
one wavelength (about 4 cm in our case)?
Cheers,
Dayton
