The output is the data image, the weight +image (which is the count of the number of pixels of the input image which +were summed to produce the single output pixel), and the absolute value image +which is the same as the data image except that the absolute value of each +input pixel is taken before being summed into the output pixel. +Rmap calculates the mean field, the mean of the absolute value of the field, +and the number of pixels in the original gram used to make the projection. +These three parameters are stored in the output "data" image header as +MEAN_FLD, MEANAFLD, and NUMPIX respectively. +.ih +EXAMPLES +1. To project an image called "im10830" and produce output images "im10830.d", +"im10830.w", and "im10830.a", one would use the following command: + +.nf + vt> rmap im10830 im10830.d im10830.w im10830.a +.fi + +.ih +SEE ALSO +readvt, quickfit, and merge. +.endhelp |
