qimager - Tool

Postscript file available tool for synthesis imaging

Description qimager is an tool that accomplishes synthesis processing. A qimager must be constructed for each MeasurementSet for which one wishes to do processing. Multiple copies of qimager may be made at any time (provide they are given different names).
