[Difx-users] Convention for DELAY, WET, DRY Polynomials {External}

[Joe Skeens]

Hi all,

I've been working on a routine that replaces the difxcalc interferometric
model with the near-field delay model given in
https://doi.org/10.1007/s00190-018-1217-0 using precise ephemerides for
satellite positions, and I have a question related to how the polynomial
models should be formulated in the .im file.

Should the DELAY polynomial include the atmospheric delays in the DRY and
WET polynomials, or should the DELAY polynomial be purely geometric, with
the DRY and WET polynomials being added to the DELAY polynomial during
correlation?

Thanks,
Joe
