Expand description

Corrections that can be performed on visibility data

Functions

correct_cable_lengths

Perform cable length corrections, given an observation’s [mwalib::CorrelatorContext] and an [’ndarray::Array3] of [TestJones`] visibilities

correct_coarse_passband_gains

Correct for coarse pfb bandpass shape in each coarse channel by scaling passband_gains to fit the coarse band.

correct_digital_gains

Apply corrections for digital gains for each coarse channel from values in metafits.

correct_geometry

Perform geometric corrections, given an observation’s [mwalib::CorrelatorContext] and an [’ndarray::Array3] of [TestJones`] visibilities

scrunch_gains

Given a set of gains for each ultrafine channel, compute the gains for each fine channel, is if these were averaged by given correlator type.
