Photometry of artificial satellites with CCD QHY-174M

ccd_stat_phot

Python scripts to process photometry obtained on CCD QHY-174M

Based on:

• astropy
• photutils
• photometry errors are estimated with wfc3_photometry procedures (https://github.com/spacetelescope/wfc3_photometry)
• astroquery

Detailed documentation can be found here

Before usage

• Virtual environment should be created and all requirements installed. Run scripts from this ENV in the future.

OR (Windows option):

• Add ccd_phot directory path to system environment, so you can use scripts right from command line if all requirements all satisfied.

Usage

1. Mark satellite on first FITS frame (Add OBJX and OBJY keywords in header). If object is not marked script will try to find it (with DAOFind func) as brightest object on the frame.
2. Prepare config_sat.ini in same directory where FITS files are located. Config can be namad in other way, but must match the mask config_satSOMETHING.ini
3. Start sat_phot.py with path to FITS files as parameter (sat_phot.py . OR sat_phot.py c:\test)
4. Make resulting plots ccd_plot.py path\\to\\result_file.phX
5. Done :)

Other arguments

usage: sat_phot.py [-h] [-c CONFIG] [-s_file START_FILE] path

positional arguments:

path Path to fits files. REQUIRED!

options:

-h, --help show this help message and exit

-c CONFIG, --config CONFIG Specify config file

-s_file START_FILE, --start_file START_FILE Specify file to start from
