In Python, I try to plot all-sky maps in Mollweide projection. I am looking to be able to show maps with arbitrarily rotated coordinates and coordinate grid. See the following generic grid image (generated in IDL) for illustration: the map center rotated first to -105 deg longitude, then to +35 deg in latitude, with the grid lines transformed accordingly.
Is there any way to realize this in Python?
I have tried using matplotlib.pyplot or the mpl_toolkits.Basemap package or cartopy package.
While all of these offer plots in Mollweide projection, with specific tailored capabilities, none of them offer the tool to rotate the center of the Mollweide map away from the equatorial plane.
