a container for field information
Internal
a Miriad observing field is expressed as an offset from a reference position
MirField is a helper class used by MirFiller and FillMetadata to hold the data describing an observing field in a single container. Most of the interaction with this class is through public data members (for programming and runtime efficiency); thus, this class is not appropriate for use outside of this module. A few helper funtions are provided to aid in utilizing the information (mainly for comparison with other MirField objects).
A Miriad dataset can contain a number of observing fields, described as offsets from a reference position. When scanning a multi-field dataset, one usually will encounter data each field as the observations cycles through the set of pointings. Thus, the filler must keep a list of unique fields that can be matched against the current field.
