New applications

DRAWSIG

Draws ${\pm}n$ standard-deviation lines on a line plot. There is clipping, and the statistics may be reported too. It is expected to be used in conjunction with LINPLOT or HISTOGRAM.

FITSMOD

Edits an NDF FITS extension via a text file or parameters. This allows you to manipulate ancillary data not in a special extension.

KSTEST

Compares datasets against a reference dataset using the Kolmogorov-Smirnov test, and combines statistically similar data into an output vector dataset. You can supply a single dataset, which is divided for the comparisons.

SUBSTITUTE

Replaces all occurrences of a given value in an NDF array with another value.
