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.

To Do

more database interfaces, rather than constants
