polcar [-b] [-c] [-d dim] [-720] [polar coord file1] [polar coord file2] ... Example: polcar 17_28.mk4.q 17_32.mk4.i This program converts a polar coordinate (r, theta) image, to a cartesian image. This is like converting a ".q" image into a ".rq" image. Note: If your image is a raw .i .q or .u cylindrical data, this progam requires the ".ba" files associated with the cylindrical data. The program automatically builds the filenames of the ".ba" files using the .q data filenames as a template. Option Flags: -b Scale to "byte" images. -c Solar disk pixels will be dark blue (instead of black). -d xdim Specify output image size (default is 960x960). -e Crop edges of field-of-view. -720 Convert any raw image to 720 rays.
