Errors may be traced during the smoothing process. An error array must first be generated. This example takes errors from the same region of the original QPOE file.
xs> errcreate ``xdata$rp110590.qp[6830:7029,9290:9489]'' rp90ab_err.imh
# The error file is rp90ab_err.imh
# The ``'' on the command line prevent IRAF's confusion with a long argument
One then sets the hidden parameters in imsmooth.
errors = yes errarray = (filename of unsmoothed error array) error_out = (filename of output error array)
