Clipping to the Final Image Size

Clipping to the Final Image Size

You may want to change the clipping dimensions, which determine the final size of the reconstructed images as well as where they are centered within the full data set. It's usually not necessary to change these, but here's how.

The easiest way to change the clipping dimensions is to write the following lines into the ".local.csh" file, changing the numbers to the appropriate values.

# width of output image setenv F_CLIP1_WIDTH 64 setenv F_CLIP2_WIDTH ${F_CLIP1_WIDTH} # height of output image setenv F_CLIP1_HEIGHT 64 setenv F_CLIP2_HEIGHT ${F_CLIP1_HEIGHT} # location of center in x direction setenv F_CLIP1_XCENTER 64 setenv F_CLIP2_XCENTER ${F_CLIP1_XCENTER} # location of center in y direction setenv F_CLIP1_YCENTER 32 setenv F_CLIP2_YCENTER ${F_CLIP1_YCENTER}

FIASCO clips twice, once to make images for alignment and once to make the final output. The F_CLIP1_ values effect the first clip while the F_CLIP1_ values effect the second.

Rather than specifying numerical sizes, you can also use the strings "whole" or "half" _WIDTH and _HEIGHT, and "center" for _XCENTER and _YCENTER.
