How to display HK data

The qcl procedure pl_ginga.qcl can be used to display any of the many permitted Housekeeping (HK) parameters (listed in appendix B), against either time, LAC count rate or another HK parameter. Note that time must be displayed on the X-axis only. One typical use of pl_ginga.qcl is to see the effect of the program cleanall (see section 2.8). This can be achieved by displaying SUD versus PI_MONI for the original and "cleaned" data cubes, and observing the effects of varying the degree of cleaning. You should notice the "outliers" on the original plot are greatly reduced by the program cleanall.

The following example plots SUD versus LAC count rate. The input file is a time series rather than a data cube because pl_ginga.qcl will only display the contents of one spectral channel, rather than the sum of many channels (see section 5.1 about compressing the spectral axis).

qcl>.pl_ginga
 
 This procedure can plot a LAC count rate or HK parameter (eg SUD,
 LATITUDE), on either axis. TIME can be plotted on the X axis only
