Calibration section

The CLASS calibration section is activated and partially filled if the metacard temperatureScale is defined. The rules are detailed in Table [*].





Table: Look-up table between the CLASS Calibration section and the Herschel-HIFI FITS. Depending on the FITS structure (pipeline level), some elements found in a FITS header or in a FITS binary table. FITS names are case sensitive. The elements not described here are set to their usual undefined value in CLASS.
CLASS Type Value Default
beeff R*4 Metacard forwardEff if metacard temperatureScale is T_A*, else 0.0
metacard beamEff if metacard temperatureScale is T_MB, else error
foeff R*4 Metacard forwardEff 0.0
gaini R*4 Metacard *sbGain (usb or lsb) 0.0
tchop R*4 Metacard hbbTemp (level 2.5) or 1st value in Column hot_cold (level 2.0) 0.0
tcold R*4 Metacard cbbTemp (level 2.5) or 2nd value in Column hot_cold (level 2.0) 0.0
