In any case, I will add stars.dat by ajtribick in the CO v.11. Obviously, this is the best variant. :smile:

Re: Updated stars.dat including Gaia DR2 data (update 2020-02-15)

It would also require changing Celestia's identifier handling: currently the HIP/encoded TYC identifier (which incidentally originated with the Pascal Hartmann catalogue) is treated as fundamental but that's not going to work with the larger catalogue as the additional stars will not be HIP/TYC sta...

This catalog was created back in 2005, and also had certain problems with duplicates. Leave it in the past.

Re: Updated stars.dat including Gaia DR2 data (update 2020-02-15)

Good to know it works on 32-bit! One way of finding out how many stars there are in a stars.dat file is to take the file size in bytes, subtract 14 (to account for the file header, which incidentally also contains the number of stars) then divide by 20. This formula works, thanks. Are you planning ...

Cool! In LukeCEL's version was 2 448 220. I.e +15 369 stars. :clap:

Added after 3 minutes 30 seconds:
I hope the accuracy of the coordinates is also at a height compared to its version. At least a little bit. :smile:

You underestimate 32-bit systems. Your database not big enough to crash with out-of-memory. :smile:

Can you tell me the exact number of stars?

I may have posted this on a previous post of CO release before but just to bump it up, here is the Horizon Problem that started with Version 7 (I think): When I just freshly landed: This problem is definitely in LUT. I checked all the available functions, but none of them came up for the solution. ...

It was enough to download and make sure that the coordinates are real.

Re: Project "Celestia Origin", release dated December 30, 2019

Since Iapteus has a mesh, it should have a Radius defined, not SemiAxes This is not a bug and is done on purpose. Iapetus model is not flattened. Makemake and Quaoar (and possibly some other objects) have the same problem as Varda I will carefully study this problem. Some names that were missed: 38...

Found an error in asteroids.ssc. for 174567 Varda: SemiAxes is given as [ 395 361.425 361.425 ]. Should be [ 395 395 361.425 ] so that Varuna is oblate rather than oblong. Your fault. :smile: In next time always specify a three parameters in your excel-file. Between major releases, we will sometime...
