It is also evident that a lot more serious GUI-based simulation code in this field is ahead of the celestia.Sci dev team ;-) ...

Oh no! I take it all back. :nono: :nono: :nono: :nono:


A huge program package like celestia.Sci will not be finished after a first release. ;-) My statement was merely to indicate that exo-planets and associated tools for their simulation will continue to play an important role in our further developments...

Specifically, what I plan for celestia.Sci is to extend the eclipse finder to a transit finder for the TRAPPIST-1 system (!!) and to simulate the photometry of planetary transits of the TRAPPIST-1 star via a Qt plotting package that we use already for our Gravitational MicroLensing displays...

Thanks for the explanation. I will continue to patiently wait for the release of celestia.Sci. :°
