ezRA’s ezGLon.py program studies cross sections of the Milky Way, along one Galactic Longitude (GLon).
ezRA’s ezGLon.py program processes *GLon.npz files.
Above, the ezGLon.py program errored because it found *Gal.npz files, but it did not find any *GLon.npz files ? At least none with any 45 +/- 5.0 degrees GLon data ?
ezCon will filter the data and create *GLon.npz files for +15 degrees GLon with a Windows command like this,
py ..\ezRA\ezCon.py data -ezConGalCrossingGLonCenter 15
ezCon will create *GLon.npz files for 15 equally-spaced GLons from 20 to 90 degrees with a Windows command like this,
py ..\ezRA\ezCon.py data -ezConGalCrossingGLonCenterL 20 90 15
Then for each wanted GLon cross section of the Milky Way, run a command, like this for GLon 20 +/- 2.0 degrees,
py ..\ezRA\ezGLon.py . -ezGlonGalCrossingGLonNear 2 -ezGLonGalCrossingGLonCenter 20
I consider ezGLon to be advanced ezRA.
This flows into 3-dimensional plotting.
Perhaps see page 92 of the SARA Journal November – December 2024, for my more detailed ezGLon instructions.
