WCSCOPY assumes that the +world coordinate system information in the header of the reference +image is accurate and that all the input images have write permission. +If the input image does not exist a data-less image header is created. +The WCS is treated as an independent object and +there is no check made on the dimensionality and sizes of the images. + + +.ih +REFERENCES + +Information on IRAF world coordinate systems including +more detailed descriptions of the "logical", "physical", and "world" +coordinate systems can be +found in the help pages for the WCSEDIT and WCRESET tasks. +Detailed documentation for the IRAF world coordinate system +interface MWCS can be found in the file "iraf$sys/mwcs/MWCS.hlp". +This file can be formatted and printed with the command "help +iraf$sys/mwcs/MWCS.hlp fi+ | lprint".
