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.|
