Function Documentation

ObitTableOTFSoln* ObitOTFGetAtmCor (  ObitOTF *  inOTF, ObitOTF *  outOTF, ObitErr *  err )

Public: Determine atmospheric opacity calibration. The offset is determined from an atmospheric model. The gain calibration is determined from the average noise cal values and the atmospheric opacity. Calibration parameters are on the inOTF info member. "SOLINT" OBIT_float (1,1,1) Solution interval in days [def 10 sec]. "TAU0" OBIT_float (1,1,1) Zenith opacity in nepers [def 0]. "ATEMP" OBIT_float (*,1,1) Effective atmospheric temperature in data units. i.e. the additional offset per airmass due to the atmosphere. per detector in units of the cal. If only one given, it is used for all detectors "MINEL" OBIT_float (1,1,1) Minimum elevation (deg) "TRX" OBIT_float (*,1,1) Receiver temperature per detector in units of the cal If only one given, it is used for all detectors "CALJY" OBIT_float (*,1,1) Noise cal value in Jy, per detector [def 1.0] . If only one given, it is used for all detectors "RAoff" OBIT_float (*,1,1) Offset in deg to add to RA [def 0] . "Decoff" OBIT_float (*,1,1) Offset in deg to add to Dec [def 0.0] . Parameters: inOTF  Input OTF data. outOTF  OTF with which the output OTFSoln is to be associated err  Error stack, returns if not empty. Returns: Pointer to the newly created OTFSoln object which is associated with inOTF.
