Hi Han,
A recent photometry report for the AAVSO which was generated for rz cas did not have any values for air mass; instead it was filled in with na.
What would be the possible cause for this na field ?
Is it possible that because the check star drifted out, that the air mass could not be calculated.

Hi Pat,

The program required the observation time and the observer longitude and latitude. Most likely the last two are missing. There are typically in the FITS header but for DSLR you have to enter them manually. you can enter them at the comet &asteroid annotation page (not logical) Just press CTRL+R (or Viewer Tools, Asteroid and comet annotation) and enter your longitude & latitude and press the Annotate.... button to acknowledge.

In next version I will try to add this option to the AAVSO report window.

Cheers, Han

Hi Han,
This is a mystery: All my images, my master darks flats, have the fields SITELAT, SITELONG and DATE-OBS filled in. I even checked this with the comet annotations page. Enclosed is a screen shot of this experiment. I can send you a small repro case of this problem with one image, a master dark and a master flat if that helps ...

Thanks always for your prompt response. I really appreciate your work.

Hi Pat,

There should be an easy fix. Can you share one of your images you load in the photometry tab. Then it will be easy for me to trace the problem and fix it.

Hi Han,
Here is the calibrated image with the site lat/longs and the date

I can also send you the master dark et flat images. .. no problem

Merci encore!

Hi Pat,

Here the airmass is reported. Maybe it is due to the fact that your using an older version. The file was solved with ASTAP version 2023.03.01. Lets first try with the latest ASTAP version. Hopefully that solves the problem. If not we have to search further.

I also noted from the report it is not using the photometry star database but the BM magnitude. Better to set in ASTAP the star database to the V50 latest version.

Hi Han,
Ok, however the install of the new software isn't working
I am running linux ubuntu vs 20.04.
I tried installing the new version; and it failed with the following

Préparation du dépaquetage de astap_amd64.deb ...
Dépaquetage de astap (2023.12.12) sur (2023.12.12) ...
Paramétrage de astap (2023.12.12) ...
chmod: impossible d'accéder à '/opt/astap/acknowledgement of databases.txt': Aucun fichier ou dossier de ce type

However I do have this file in /opt/astap
**ls -alt acknowledgement_of_databases.txt
-rwxrw-r-- 1 root root 34640 Apr 8 2023 acknowledgement_of_databases.txt
$ pwd
/opt/astap
**
Could you please help me install the new version ?

Note also that I downloaded the V50 database. But I already have the H18.. so I'm waiting to get your direction --- what should I do about the db situation

awaiting your response
Pat

Hello Pat,

That is weird. I have looked here to the attributes of the file "acknowledgement_of_databases.txt ". It had a strange attribute" Maybe because it was copied from Windows. I have fixed that.

To fix your problem. Download a fresh copy of the installer:
https://sourceforge.net/projects/astap-program/files/linux_installer/astap_amd64.deb/download

This should hopefully fix your install problem. If not try this command first:

sudo rm "/opt/astap/acknowledgement_of_databases.txt"
Then reinstall the version from above.

That should hopefully fix the install problem and airmass missing problem. Tell me if this works for you.

Hi Han,
Problem persists with the build you posted.
Fortunately I saved the old one, and it installs correctly. I can run astap

Perhaps we should go with a tarball (tar gvfz,etc ) and you can coach me on how to install

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

han.k - 2023-12-13

I tried here the alternative install method:

sudo dpkg -i astap_amd64.deb

and got the message that it can not find this file ( to set the attributes):
/opt/astap/acknowledgement of databases.txt

Must simply the wrong filename. I will fix it.

I have fixed the path. Can you download the installer and try again?

Hi Han,
First problem fixed - no errors shown in the install. But it now looks like a dependency problem which fails when I try to run astap - see the following

Hi Pat,

Since March this year I changed from Lubuntu 20.04 to 22. I was not aware that this is causing problems. I could compile again under 20.04 but let first try something else:

sudo apt update
sudo apt install libc6
It automatically installed 2.35 for me.

I found this solution at:
https://stackoverflow.com/questions/71940179/error-lib-x86-64-linux-gnu-libc-so-6-version-glibc-2-34-not-found

Can you try those two steps. If that doesn't work, then I will compile in Lubuntu 20.04. (virtual machine). No problem.

Hi Han,
Unfortunately the GLIBC is tied to the ubuntu version:
...
I followed your instructions:
sudo apt update
sudo apt install libc6
My system is up to date:
sudo apt install libc6
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances

libc6 est déjà la version la plus récente (2.31-0ubuntu9.14).

and when I checked this:

Would this be possible ? That would be greatly appreciated

This version is compiled under 20.04 and should work. Tel me if this works.

Hi Han,

I think we have good news!
Your version for Ubuntu 20.04 was successfully installed. Note that I am still using the database H18

The not-so-good news is that the airmass is still na.

But the great news is that we have a repro case !!! :)

I shall send you the whole package (just zip up the directory ) and mail it to you via we transfer.

Hi Han,
The We Transfer delivery failed. Could you please provide an email address to which I can send the zip file ?
Thanks

Hi Han,
You should have received a link for the repro case - photometry of rz cas

By the way - I have several examples of photometry where the airmass has been calculated... so maybe we can do a comparison to find the problem.

I have the images. The airmass is calculated for the calibrated (..cal.fit) files but not for the original files. That is strange. I will follow the calculation through the debugger to trace the problem.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

No the airmass is calculated for all files. I will switch to Linux to see if it make a difference.

What decimal seperator is your computer using. A comma or dot. So if you calculate 10/3 do you get 3,333 or 3.333?

In Linux it is also working. Are the time and Centalt columns filled like as in attached screenshot?:

Hi Han,
Progress! The first 7 images have no centalt or airmass, the rest do.
All stars have Date JS and HJS
