I see that you released a new v2022.08.02 Mac version. Thanks.
I installed it but it seems to still have an issue which I don't seem to be able to reproduce. After stacking and plate solving (but not saving) I looked at the header and saw:
CALSTAT = 'DFDFDFDFDFBS'
Not 100% sure it was the DF that was repeated but I think that was it. I also think it was repeated 5 times which was the number of Lights I stacked.
As I said, I haven't been able to reproduce it but it was real. Maybe something will spring to your mind about how that could happen.
The good news is that the CALSTAT field is not cleared when saving the header. Yay!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
OK, one more change in the new version that may be a bug.
I think that after a Solve, ASTAP would automatically display the RA/Dec grid. It no longer does that. However, if you Save the header and then reload the file, then the grid is automatically displayed. Was this intentional?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Han,
I noticed that "Save new header" after doing a plate solve loses the CALSTAT info. Before the plate solve it was
CALSTAT = 'DFBS'
It was still this after plate solving, but after Save new header it became
CALSTAT = ''
Is it supposed to do that? The AAVSO submission interface needs the CALSTAT info to be there.
Looks like you found a bug. I will fix it.
Hello Bill,
I tried to reproduce it but I can't at the moment. Can you describe more in detail the steps you did to get this effect?
Han

CALSTAT is still correct.
Clicked Save Header and now the CALSTAT is blank.
Hope that helps.

Okay, I found it. Fixed in version 2022-08-01a (Windows) just uploaded.
Thanks for the feedback.
Han
Great!
I need the macOS version (Intel processor). If you can build that at some point it would be much appreciated.
Bill
Hi Bill,
I will do some code optimisation the next hours and release a Mac version today
Cheers, Han
I see that you released a new v2022.08.02 Mac version. Thanks.
I installed it but it seems to still have an issue which I don't seem to be able to reproduce. After stacking and plate solving (but not saving) I looked at the header and saw:
CALSTAT = 'DFDFDFDFDFBS'
Not 100% sure it was the DF that was repeated but I think that was it. I also think it was repeated 5 times which was the number of Lights I stacked.
As I said, I haven't been able to reproduce it but it was real. Maybe something will spring to your mind about how that could happen.
The good news is that the CALSTAT field is not cleared when saving the header. Yay!
OK, one more change in the new version that may be a bug.
I think that after a Solve, ASTAP would automatically display the RA/Dec grid. It no longer does that. However, if you Save the header and then reload the file, then the grid is automatically displayed. Was this intentional?
This is a bug in the last version. I localized many variables but resulted in one more bug. I will update the Mac version.
I have released version 2022-08-03 for the Mac. Hopefully no more bugs left. Tell me if you find something else. :)
Cheers, Han
Han,
Thanks for the quick support. The problems I mentioned appear to have been fixed I will bang on it some today and let you know if I see anything else.
Bill
