PROCESS_FITS
Category b |
Version 3.0A2 |
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 8- or 16- bit image to the IMAGEFILES directory
The 12-character picture name consists of a one-character camera identifier, a 9-character ephemeris time, and a two-character filter identifier.
The data stored in each image file contained in the IMAGEFILES directory is a scaled unsigned integer (2 bytes or 16 bits), with the exclusion of values less than 0. Acceptable values are from 0 to 32767.
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 32767 to maximize the accuracy of the stored data.
Required Files
- FITS image file - You provide the name as part of the standard input.
Outputs
a row for the image is appended to make_sumfiles.in
raw 16- or 18-bit image(s) are stored to IMAGEFILES directory
Using process_fits
Here is a sample of the standard input:
