NAME

rmap -- Project a full disk gram into a 180x180 flat image

USAGE

rmap inputimage outputimage outweight outabs

PARAMETERS

inputimage
Name of image to be projected.
outputimage
Name to give output data image.
outweight
Name to give output weight image.
outabs
Name to give output absolute value image.

DESCRIPTION

Rmap accepts as input a full disk carrington gram in a 2048x2048 IRAF image and projects it into a 180x180 IRAF image such that the lines of longitude and latitude are straight lines. 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.

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:

	vt> rmap im10830 im10830.d im10830.w im10830.a
