Adds systematic errors to a Ginga data cube, time series or spectrum. Generates background data for a particular Ginga data cube or time series. The program bgdmfit must be run prior to bgdsim . A qcl procedure to subtract Ginga data cubes or time series using standardised files. It should be used when no local background is available, or for cases where the background subtraction is not important.
Time orders a catalogue file.
Removes poor quality data from a Ginga data cube or time series. Algorithims are taken from Numerical Recipes' subroutines Spear and Pearsn. Performs divisions on a Ginga data cube, time series or spectrum. Folds a section of a Ginga data cube or time series on a given period. The output file contains the folded light curve and can be used as input for the program ginga2xsp to produce phase resolved spectra.
