I have added it to the solve function. The mean hfd is maybe 20% higher then the median hfd . Therefore I have used the new keyword HFD_MEAN. So you can compare it with HFD from the analyse function. Tell me if this works for you. https://www.hnsky.org/astap_setup.exe cs, Han

Hi Jesse, HFD and FWHM are currently only added by batch mode to add tilt value and the the tilt measurement activated by F4. It is NOT added after solving. To add it after solving, I have already in the code the mean/average HFD values after solving but it is not stored in the header. I need to finish some complicated changes in the code first and then I will add the mean HFD after solving. The median HFD is not calculated after solving since it would be waste of processing power. The mean is much...

What I tried to say, I can look if the mean HFD can be reported after solving.

Hi Jesse, In made a coding error. The HFD report was not always reported during analyse. I have corrected that and it should work for your star poor images. For both F4 analyse and batch tilt measurement. I have also added the median FWHM. https://www.hnsky.org/astap_setup.exe It is currently not executed for astrometric solving! I have only the mean HFD value after solving. Not the median since it will take more processing time. I can look tomorrow if that could be added after solving. cs

I have modified the Window development version. 1) Added the keyword HFD. 2) Added a message not enough stars for tilt https://www.hnsky.org/astap_setup.exe Other operating system will follow soon. I'm making some other changes. cs, Han

The number of stars is too small. There are nine areas and I assume one area mid & right is too empty. This is quickly tested with the F4 button. I have no problem to add HFD keyword, but is it useful? You could add the images to the tab lights. Hit the button analyse (quick unselected) and you get all HFD values. Then you could select all (ctrl+A) and copy & paste all info including HFD to a spreadsheet. If you have an other tool which could read keyword HFD, then I will add it. cs, Han
