Etymology

Class name is short for Miriad history reader.

Motivation

Miriad history is read independently from the visibility data; thus, an independent class is in order. This class hides the details of how to read Miriad history.

Synopsis

This class is used to extract history from a Miriad visibility dataset. Normally, an application does not create this class by itself, but rather via MirVisReader::openHistory();
