The first few lines of each .pro file contain a header with a description of the routine and general instructions for its use. These can be accessed within IDL by typing "doc_library,"routine name"" or via the links below. Joel Bergé has written a PDF manual covering many aspects of shapelet-based image processing with this code. I am slowly completing the on-line documentation here, but if the information you want is not yet available, please ask me at r.j.massey [at] durham.ac.uk. The help files will grow mainly through answers to such questions.
| decomp: | — Transform images into shapelet space and back. |
| decomp/focus: | — Automated n_max-beta finder, optimising chi^2 for a decomposition as in "Polar Shapelets". |
| decomp/polar: | — Conversion between Cartesian and polar shapelets. |
| alias: | — Wrapper routines used to maintain backwards compatability with old versions of the code. |
| io: | — Data I/O from disc, and conversion of structure types. |
| operations: | — Image manipulation and transformations in shapelet space. |
| pipeline: | — Object detection and decomposition within an entire astronomical image. |
| plotting: | — Various plotting tools. |
| properties: | — Shape analysis and galaxy morphology indices. |
| library: | — Standard IDL library routines, including some from the IDL Astronomy User's Library. |
