Malcolm - 2022-04-23

Hi,

I have a problem using "Unknown Star Annotation" I get an error message "ut is an invalid integer" I have seen this before, or in the forum, any idea what is causing this? All other annotations are working fine.

Regards

Malcolm

Hello Malcom,

I don't see it here. Can you share the image which causes the error? E.g. upload to

https://ufile.io/

and share the link.

  Hi Hank,
  
  I tried to attach it to the email, and I have uploaded the error dialog.

The PNG is not usefull. To find the cause I like to reproduce to error and for that I need the same astronomical image you have used. You can attach the image also in this forum but do not send it by email. Or just upload it to

https://ufile.io/

and give me the link.

Better not to reply by email because the email adresses will be shown in the forum.

  Hi Hank,
  
  I simply solve an image then click on "Unknown Star Annotations" then the dialog appears. I am hoping to see if I captured anything that is not recognised.

  Three linked images, also below are the procedures I use:
  
  Solve
  
  Magnitude annotations
  
  Clean
  
  Deepsky Annotations
  
  Unknown Star Annotations.

Hello Malcom,

I tried to download the files but the link is wrong. Can you retry to upload again?

Hi. I have exactly the same problem as reported in the original post. i.e when I go to "Unknown Star Annotation" I get an error message "ut is an invalid integer" .

How can this be solved?

Hello Luke, can you upload or share the image so I can reproduce the error? At the moment i don't see the error here.

Hello Luke, Malcom,

Without an image i can't reproduce the error at the moment. Please share one.

  I posted some images last week. I have tested the links and they are working OK.

Hello Malcom,

Yes the files I can download but it are all screenshots. I need the original result_Siril.fit file. Can you provide this file?

At least I can see it is a stacked colour file from Siril.

  Sorry, I have just been inputting RAW FIT Files from Astroberry which are CR2 RAW Converted already. Maybe this is the issue. The RAW FIT conversion is part of the latest Astroberry release and has lowered my time to carry out imaging and conversions for DSS, Siril and ASTAP.
  
  I will check on earlier CR2 Files and get back with the result. I will also post images after the completion of further testing

  Hi Han,
  
  Here is the link - https://ufile.io/01fr1qle for the FITS Files I was able to solve but had the error. I have not yet tested the other as yet. Will do you sometime today and post the result.

    Hi Han,
    
    Tried a CR2 File that I was able to solve, and this also came with the same error, the file is - https://ufile.io/050pehha
    
    Can you send me a link to a working file that you have in your system, along with Focal Length and Pixel size?

Hello Malcom,

Both files are not given any errors here, so I'm a little puzzled what happening at your side. Can you give me a screenshot of ASTAP tab alignment in the stack menu (ctrl+A)

Can you check if the solution matches by "Star (database) annotation"ctrl+N The circels should match with the stars. Maybe your solution is totally wrong due to settings change. E.g tolerance too high.

I have seen only one FITS and one TIF file but not the CR2 but I don't think that matters

Please reply on the forum, otherwise the email address's will be shown. I have edited you post's to remove those email addresses.

I have to leave now and will come back later in the day.

Hi Hank,

Sorry for the delay, been hectic here, attached are the two photos one of the Stack Method and the other for Pixel Math (mainly for the field of view which is perfect).

Unfortunately the alignment tab is not there.

I'm reworking the "unknown star" menu to improve it. Just to make it work better. Maybe it helps with your error but I will release it tonight or tomorrow anyhow.

You could try this Windows version 2022-05-04:

Hi Hank, Tried the new version, unfortunately no difference my end. Attached is a image of the Alignment TAB.

That looks all normal. Maybe there is something wrong with the annulus setting in the photometry tab.

Can you try the option "Show extend solver log" See red marked in attached image. Try then menu "Show unknown stars". Then copy the loq and post it here. Hopefully that tells something.

The next step would to go to default settings. In the viewer, go to menu FILE, SETTINGS, GO TO DEFAULT SETTINGS. Maybe it is good for the record to save the setting first to something else like default2.

Hi Han,

I decided to carry out a few tests myself and After setting the "Star database used" to H17 the problem did not happen. It only occurs when it is set to Auto.

I compared the logs between the failed one and the good one and there is no difference.

Good Test (H17) Similar test done for (H18) same results:

21:35:23  Median HFD is 6.7. Aperture and annulus will be adapted accordingly.
21:35:23  Photometry calibration for POINT SOURCES successful. 5022 Gaia stars used for flux calibration.  Flux aperture diameter: 20 pixels. Coefficient of variation: 0.58%. Annulus inner diameter: 39 pixels. Stars with pixel values of 65535 or higher are ignored.
21:35:23  Limiting magnitude is about 18.8   (7σ, aperture ⌀3.0)

Bad Test (Auto):

21:34:08  Median HFD is 6.7. Aperture and annulus will be adapted accordingly.
21:34:09  Photometry calibration for POINT SOURCES successful. 5588 Gaia stars used for flux calibration.  Flux aperture diameter: 20 pixels. Coefficient of variation: 0.61%. Annulus inner diameter: 39 pixels. Stars with pixel values of 65535 or higher are ignored.
21:34:09  Limiting magnitude is about 18.8   (7σ, aperture ⌀3.0)

Good , that is an helpful observation ! Now I can now repeat the problem here. It will be easy to solve.

For unknown star detection, you best use the H18. I noted some stars are missing in the database. I investigated and these star magnitude was unreliable and excluded from the ASTAP database.

This is now fixed in version 2022.5.9 just uploaded.

It tried to read the limiting magnitude from the word auto instead of h18. The letters ut can't be converted to a number.
