CALL: PLOT_ERROR_BAND
The 3 argument vectors should all have the same length, and
should contain respectively the x-coordinate, the lower y of the
band for this x and the higher y bound of the band for this x.
The minimum permissible length of the vectors is 2, the
maximum depends on the compilation parameter MXLIST (usually
set either to 200 or to 1000 depending on the Patchy flag
LONGLIST) and is equal to (MXLIST-1)/2.
The vectors should be 1-dimensional; matrices with another number
of dimensions are unfolded before use.
This procedure does not accept scalar arguments.
