Prerequisite

• Measure class
• MeasFrame class

Etymology

From Measure and Frame

Synopsis

The MeasFrame class contains the 'when and where' of an observed Measure. Calculations to get the appropiate value (e.g. the Earth's longitude) from this frame for conversions are done in this class, together with all the caching of (intermediate) results that can speed-up calculations.
The MCFrame class is used by the individual measure conversion classes (see MCBase class).

Example

        MEpoch my_epoch(Quantity(MeasData::MJDB1950,"d")); // an epoch
        MCFrame frame(my_epoch);        // used in a frame
        frame.set(obser);               // add observatory (an MPosition)
        MEpoch::Convert conv(my_epoch, MEPoch::Ref(MEpoch::LAST, frame));

The conv conversion engine will (transpararently) use the MCFrame class in calls from MCEpoch (the time conversions), which will be called by the MEpoch::Convert () operator.

Motivation

To separate the frame calculations from the Measure containers, to enable e.g. Tables to have Measures.
