CHANPHA> analogue_gain
CHANPHA> gain_coeff
CHANPHA> resolution_coeff
CHANPHA> collimator
Commands to change entries in the EXOSAT ME and GSPC detector packages.
They prompt for new values of the analogue gain setting (for each ME
detector used for the spectrum), for new gain coefficients of the GSPC
or the ME detectors, for new resolution coefficients for ME
detectors and for new collimator efficiencies, respectively.
The collimator command also updates the effective area in the `file
info' package.
