static

A wrapper for regridChanBounds() which takes the user interface type re-gridding parameters The ready-made grid is returned in newCHAN_FREQ and newCHAN_WIDTH.

Parameters

newCHAN_FREQ	Output
oldCHAN_FREQ	casacore::Input (original grid)
phaseCenter	Re-gridding parameters
mRV	Additional radial velocity shift to apply, used e.g. when outframe=="SOURCE"

Calculate the final new channel boundaries from the re-regridding parameters and the old channel boundaries (already transformed to the desired reference frame).

Returns false if input parameters were invalid and no useful boundaries could be created

The following inline convenience methods for regridSpw bypass the whole CASA measure system because when they are used, they can assume that the frame stays the same and the units are OK.
