No point spread function fitting techniques are employed. +The photometry routines are most suitable for use on uncrowded +or moderately crowded fields. + +The apphot directory structure is listed below. The package organization +is by task, for example the center subdirectory contains routines +specific to the center task or by function, for example the nlfit +directory contains the non-linear least squares fitting routines. +The wphot task shares alot of code with the phot task. Similarly +the polymark task shares some code with the polyphot task. +The .h files are all in lib as many of them are shared by several tasks. + + |-aplib---------apphot routines used by several tasks + |-aputil--------miscellaneous useful routines + |-center--------routines specific to centering, the center task + |-daofind-------routines specific to the daofind task + |-doc-----------apphot documentation +|-apphot-----|-fitpsf--------routines specific to the fitpsf task + |-fitsky--------routines specific to sky fitting, the fitsky task + |-lib-----------apphot definitions or .h files + |-phot----------routines specific to the qphot/phot tasks + |-polyphot------routines specific to the polyphot/polymark tasks + |-radprof-------routines specific to the radprof task + |-wphot---------routines specific to the wphot task + |-test----------directory of test data + + +Lindsey Davis +NOAO IRAF GROUP +November 1991 -- cgit
