        /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:
