MODSHOW

        [WEEDS\]MODSHOW [/PEN Ipen] [/SCALE AUTO|KEEP]

    Plot the results of MODSOURCE over the current spectrum.

    The command ensures that the X-axis range and Y-axis range are fixed  so
    one can compare the predictions of the model with the observed spectrum.
    The current Y scale is kept by default (/SCALE KEEP), but it can be  au-
    tomatically  recomputed if the model requires a larger range (/SCALE AU-
    TO).

    The model is drawn with the pencil 1 by default (plain line,  red  color
    at start), but this can be changed with the /PEN option.
