OPTIONS /GAINIMAGE

    /GAINIMAGE gainImage [dB]

    Specify the gain ratio of image to signal sidebands.

    Real      :: gainImage         !

    If "dB" is added after the value, the ratio is assumed to be in dB,
    otherwise a decimal fraction.

    Simple standard values for these gain ratios can be found on the IRAM
    30-m web pages (Telescope Summary). If you need accurate values for the
    single-pixel heterodyne receivers, you should measure them with:
    CALIBRATE /GAINIMAGE receiverName
