Available Commands

Currently, the following commands are available within CUPID:

CUPIDHELP

- gives on-line help for all CUPID commands;

EXTRACTCLUMPS

- calculates parameters for the clumps within a 1, 2 or 3D data array, given a mask array that identifies the pixels within each clump;

FINDBACK

- applies spatial filtering to a 1, 2 or 3D array in order to remove features smaller than a specified size and thus produce an estimate of the background within the NDF;

FINDCLUMPS

- finds clumps within a 1, 2 or 3D array and produces a mask identifying the pixels included in each clump. Also produces a catalogue of clump parameters. Various clump identification algorithms are supported such as ClumpFind, GaussClumps, etc.

MAKECLUMPS

- creates a 1, 2 or 3D array containing a collection of random Gaussian clumps, with added noise.

OUTLINECLUMP

- draw an outline on a previously displayed image around a 2-dimensional clump.
