Detailed Description

Defines the atomic element of the visibility data class. This contains the RR, LL, RL, and LR visibilities with various additional accoutrements. This will be passed to all objects that require a visibility data value (e.g., likelihoods) and therefore can accrete additional elements but cannot rearrange elements internally to ensure backwards compatability. Because data must never change during analysis, all elements are necessarily consts, requiring some minor gymnastics at initialization.

Within the datum_visibility class, station codes are arbitrary, but elsewhere may be assumed to correspond to either the one- or two-letter station codes identified in https://eventhorizontelescope.teamwork.com/#notebooks/97662:

List of one- and two-letter EHT station codes.

The visibilities are pre-rotated by the the field rotation angle, and thus this must be folded into subsequent D-term calibration.

The documentation for this struct was generated from the following files:
