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 an unsigned integer (14 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:
