Paolo Grigis' list of (a few) useful IDL programs. All programs have the prefix "pg_" to avoid name conflicts with other programs.

PG_PLOTIMAGE

Simple program for plotting a 2-dimensional image with coordinates given by two one-dimensional (possibnly irregular) vectors x and y. Optionally, log scaling in both axes is possible.

PG_2DIMFFTCORR

Computes the cross-correlation between two 2-dimensional arrays (using the FFT method).

PG_FIT2DIMPARPEAK

Quadratic fit of the maximum position of an array.
