= PROCESS_FITS = ||Category B ||Version 3.0.1 || == Description == This program * reads a FITS image file * extracts relevant information from the header * adds a record to the [[make_sumfiles.in]] file * adds a raw 16- bit unsigned integer image to the [[IMAGEFILES]] directory [[SPC-OREx Naming Convention]] === Level 0 === The data stored in each image file contained in the [[IMAGEFILES]] directory is a scaled unsigned integer (as 14 bits folded into 16 bits), with the exclusion of values less than 0. Acceptable values are from 0 to 16,383. === Level 1 === If the source is a real (or 32-bit float) value '''process_fits''' takes the original images' data float and calculates the maximum value. Then it scales the data to spread from 0 to 65536 to maximize the accuracy of the stored data. == ECR Changes from 3.0A2 == * Support OREx level 0 images * Trim the second channel from the image to make it 1024x1024 * Remove dark/bias -- This comes from the shielded overscan region * Correct the flat field * Desmear the image === Required Files === * FITS image file - You provide the name as part of the standard input. * DATA/[[DN2TEMP.TXT]] * DATA/[[FLATFILES.TXT]] === Outputs === * a row for the image is appended to [[make_sumfiles.in]] * 16 image(s) are stored to [[IMAGEFILES]] directory.(JRW edit: Do you mean 16-bit image?) Stretched from 0 to 65536 = WARNING == * The program [[display]] will put the 0,0 position of the image in the top left, but OREx wants 0,0 to be in the bottom left. ---------- == Using process_fits == process_fits can be run in two modes * Single file - just give the FITS filename at the prompt * Batch mode * If the file [[newpic.txt]] exists, then process_fits will search through ../OSIRIS_REX/NEW_IMAGES to find the image and process. [[NEW_IMAGES]] is configured as YYYY/DOY/ Here is a sample of the standard input: {{{ Input filename 2019-01-20T22-47-05.541_PCAM_L0b_V004.fits OKAY 2019 JAN 20 22:47:05.050 EXPOSURE(ms) = 100.000 MSB SIGNED 0.00 0.00 0.00 0.00 0.00 5.0000000000000000 P601296494J3 }}} ---------- [[process_fits-3.0A2]] ''(Compiled by KD)'' ---- CategoryThreeOhOne
