Etymology

MeasTable from Measure and Table

Synopsis

MeasTable contains the database interface for all data necessary for precession, nutation and other Measure related calculations.
All data are obtained by calls to a method. E.g. fundArg(1) will provide the first fundamental argument for nutation calculations, i.e. 'l'.
This class contains no constructors or destructors, only static methods and (static) constants.

V.S. Gubanov, Astron. Zh. 49, p1112, 1972

Where strings are passed in as arguments (observatory names, sources), they will be case insensitive, and minimum match.

Example

Usage examples can be found in Precession

Motivation

To create a clean interface between the actual calculations and the methods to obtain the parameters for these calculations. Note that the tables are in general in the format and units found in the literature. This is to be able to easy check and change them. However, in the future re-arrangement could produce faster and more compact code.

static Bool casacore::MeasTable::AntennaResponsesPath ( String antRespPath,

static

Get absolute path to AntennaResponses table of observatory nam.

It returns False if no valid path can be found or the observatory is unknown. If the observatory is known, antRespPath will be set to the entry in the AntennaResponses column of the Observatories table even if it doesn't describe a valid path; if the entry is not an absolute path, the data directory name will be prepended and validity verified.
