Dear the system admin

Hi, my name is Tan. I have a question.
Can it possible to convert a CEL coordinate value to GAL coordinate value by python code? If possible, how can I use it?

Thank you for reading me.

The answer is yes.

See http://cta.irap.omp.eu/gammalib/howto/sky.html#how-to-convert-sky-map-projections. Just replace the HEALPix map in the example by a WCS CEL map.

I recognized that this does maybe not answer your question, as you were asking about coordinates, not maps. Here is how to do this with coordinates:

dir=gammalib.GSkyDir()
dir.radec_deg(83.63,22.01)
l=dir.l_deg()
b=dir.b_deg()
print(l,b)

Maybe we should add a respective section in the documentation?
