## Display calibration loads

The loads of a calibration scan can be displayed in a plot with e.g. the command:

    MRTCAL> @ plot-loads iram30m-4mhz-20100930s200-imb.fits

The result is shown in the Figure . It shows the load values as found in the `DATA` column of each subscan. They can be averaged (i.e. display a single average load) or not (i.e. display all the single dumps) thanks to the option `/AVERAGE YES|NO` (default is `YES`).

Figure: Resulting plot of the procedure `@ plot-loads`. The X axis is not increasing frequency, but chunks as found in the IMB-FITS. They have to be reordered and reoriented to get the final frequency axis. The mean load value per chunk is also displayed in black, overlaid to each chunk load curve.
