tarestore -- Restore a 96 x 64 FOS Mode I image.
tarestore input output_y output_x
The tarestore task is used to reconstruct an FOS Mode I picture for target acquistion. This task explicitly assumes that the input image was obtained by an observation with quarter-stepping in the X direction, and a Y-step of 1.5 microns. The input image is trimmed to eliminate diodes not on the aperture. The task first restores in the Y-direction and produces an intermediate image. The task then restores the intermediate image in the X-direction. The actual restoration involves matrix-mulitplication by two reference images.
- input [file name]
- Input image. This may be either a raw (d0h) image with dimensions 96 x 64, or a calibrated (c1h) image having 64 groups of 96 pixels each.
- output_y [file name]
- Output image from restoration in the Y-direction. This image has dimensions 51 x 48.
- output_x [file name]
- Output image from restoration in both the Y- and X-direction. This image has dimensions 48 x 48.
- (trim = 23) [integer]
- Number of left-hand columns to trim from the input image. Current understanding of the commanding of a Mode I target acquisition indicates that the first 23 columns will not fall on the aperture and should be trimmed. The top row (64) of the image is also trimmed.
- (magic_y = "scidata$ymatrix.hhh") [file name]
- This is the "magic matrix" used to multiply the trimmed input image and perform the Y-restoration.
- (magic_x = "scidata$xmatrix.hhh") [file name]
- This is the "magic matrix" used to multiply the Y-restored image and perform the X-restoration.
- (label= "tmp$modeone_1.dat") [file name]
- Temporary file containing labels for raw (input) image for use by the modeone task.
- (label= "tmp$modeone_2.dat") [file name]
- Temporary file containing labels for output_y image for use by the modeone task.
- (label= "tmp$modeone_3.dat") [file name]
- Temporary file containing labels for output_x image for use by the modeone task.
1. Restore the calibrated Mode I target acquisition observation, y00vk10hr.c1h, producing the intermediate Y-restored image, 10h_y.hhh, and the final X- and Y-restored image, 10h_xy.hhh.
