Roundess by CLI

[Andre Germain]

Very handy to use astap_cli for automation via scripts, and if roundess (eccentricity) was available via CLI would be a great addition.

Hi Andre,

The philosophy has been to keep the astap_cli version a pure solver. Secondly I was never so happy about the roundness measurement algorithm. This is pretty difficult for a star like object. But since unroundnes is also measurable by the HFD values, I would recommend to just use the HFD measurement:

Analyse options:
-analyse snr_min {Analyse only and report median HFD and number of stars used}

To analyse a FITS file you could do in a Windows batch file the following:

c:\astap.fpc\astap.exe -f c:\astap.fpc\test_files\command_line_test\m16.fit -analyse 30
echo Exit Code is %errorlevel%
pause

You will get
Exit Code is 326000666

where the HFD is 3.26 using 666 stars

For Linux and Mac a stdout is used reporting as follows:

HFD_MEDIAN=3.3

STARS=666

-analyse functionality:
Program Windows Linux macOS
astap exit code stdout stdout
astap_cli exit code & stdout stdout stdout
