More than one ephemeris file at the same time

[roe-dl]

Is it allowed to do something like this?

t = ts.now()
eph1 = load('de440s.bsp')
eph2 = load('mar097.bsp')
x = eph1['moon'].at(t).observe(eph2['phobos'])

(This is to make the example short. There is no special sense in it besides using different ephemeris files)

Yes, it's allowed! (Did you get an error when you tried?)

[roe-dl]

Thank you.

No, no error. I wondered if the different files fit together.
