## 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
