These subroutines convert from chip coordinates (ie, the RAWX/Y or PIXCOORD1 system) to instrument-centric coordinates, the latter being either the DETX/Y (the same, up to a scalar multiple, as the CAMCOORD2 system) or the TELCOORD system, depending on which of the optional variables , , and the caller has supplied. The cal calls CAL_rawXY2mm and CAL_camCoord2ToTelCoord are employed.

NOTE this function requires the cal to have been set to the correct instrumentId, ccdChipId and (if instrumentId is EMOS1 or EMOS2) ccdNodeId before the call.
