Dear Pavel,

Thank you for your reply, please correct me if I'm wrong. From my quick glance on your script its looks like your are compiling data from various repository and using it to create a new stellarium star catalog with added information or for other means. But it looks like the output/input to mysql are in plain text file. How do you incorporate those output to stellarium, you know, since stellarium using hex format.

Again plese correct me if I'm wrong.

Thank you.

Dear Ammar,

3 or 4 years ago I played with personal customization of Stellarium as well. Originally I just wanted to have Aitken and Struve numbers available and variable stars name search. I have no time for it now. You can search for my email in the sourceforge archive. I downloaded plethora of text catalogues from CDS, loaded them to MySQL and made query scripts over the tables, that provided interested data. I still found the description of the work and the scripts in my archive, attaching 3 text files, check them if they are of any use to you. (Knowledge of MySQL is necessary). You find that names.fab approach has its limitations (I believe the issue I raised when reporting was still on sourceforge was never fixed).

I think Virgo provides similar functionality but, alas, you have to be online. I made my customization for myself, always being offline.

Cheers,

Pavel

Dear Ammar,

it's far simpler. Star names are part of a sky culture, therefore they are
stored there, in the star_names.fab file. This is a text file which lists
Hipparchos numbers and the given name.

Kind regards,
Georg
