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
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. 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
Here is a sample of the standard input:
