Stellarium

Measurement uncertainty

Asked by Pablo

HI, good afternoon
I have a project in my university, I will make a astrolabe...I need to know how Stellarium calculates the data of the stars specially I need know the uncertainty....Where can I know more about of Accuracy, precision, exactitude of Stellarium? I want calibrate my astrolabe with respect of Stellarium.

Thanks for your time.
I hope a answer
Have a good day.

Google: Stellarium accuracy
Google: Stellarium star catalog

Is there anything that has not been said a hundred times?

Source for computing: various standard literature for the topic, e.g. Meeus: Astronomical Algorithms, Seidelmann: Explanatory Supplement to the Astronomical Ephemerides, Heafner: Fundamental Ephemeris Computations, Duffet-Smith books, bits of other open-source software.

Astrolabes are great, but typically are accurate to the minute at best. (I have programmed about 8 layouts and built 35 myself.) Stellarium should already well suffice for comparisons, although things may get more interesting when you compare star positions in antiquity. Still, I repeat you should not calibrate anything against Stellarium until we say you can. ;-)

Please keep one question in one thread. Can we delete your 2 other questions?

Can you help with this problem?
