How to start scripts

There are few ways to start scripts from this project and begin processing FITS files.

Instruction for Windows users:

1. Start script from CCD_PHOT directory (install dir).

   If there is only one Python environment in you PC ecosystem. That means you have installed Python only for processing photometry files and will not install any other Python packages.

   Navigate to the installation folder CCD_PHOT and start any script with expected arguments. Example:

   python3 sat_phot.py path\to\fits\files
   

   You can also add CCD_PHOT directory to your system PATH (how to: env_link) and use scripts from any directory. For example if you are located in directory with your FITS file, than just do:

   python3 sat_phot.py .
   

   Where . means - use current working directory

2. Use virtual environment.

   If you create and setup virtual environment, as it described in install section, you can use it to lunch the scripts. In this case you will never had experience of Python packages version conflicts.

   For example you call your virtual environment venv as it proposed in install section.

   You can activate your virtual env from ccd_phot dir

   .\venv\Scripts\activate.bat
   

   and than start any script

   python script_name.py arguments
   python sat_phot.py arguments
   

   This is enough or, if you need to start your virtual env from any other dir, you can make bat file (example ccd_python.bat with code below). Change PROJECT_ROOT to find your ccd_phot directory. Add ccd_phot directory to your system path (see: env_link). Then, in any directory, you can type:

   ccd_python script_name.py arguments
   

   For example:

   ccd_python sat_phot.py . -c config_name.ini
   

   Code of ccd_python.bat:

   @echo off
   
   :: Define your project root path
   set "PROJECT_ROOT=path\to\ccd_phot"
   set "PYTHON_EXE=%PROJECT_ROOT%\venv\Scripts\python.exe"
   
   :: Check if script name is present (original %1)
   if "%1"=="" (
      echo Error: No Python script name was specified.
      goto :eof
   )
   
   :: Construct the full script path using the initial %1
   set "SCRIPT_PATH=%PROJECT_ROOT%\%1"
   
   :: --- Validation Checks ---
   if not exist "%PYTHON_EXE%" (
      echo Error: Python interpreter not found at: "%PYTHON_EXE%"
      goto :eof
   )
   if not exist "%SCRIPT_PATH%" (
      echo Error: Script not found at path: "%SCRIPT_PATH%"
      goto :eof
   )
   
   
   setlocal ENABLEDELAYEDEXPANSION
    set "_args=%*"
    set "_args=!_args:*%1 =!"
   
   
   "%PYTHON_EXE%" "%SCRIPT_PATH%" %_args%
   
   endlocal
   

Instruction for Linux users:

Help yourself in a way you like the most :).

You know how to deal with it.
