(readExtinction.py): add method to plot distance "resolution" #12

Closed willclarkson closed 3 years ago

willclarkson commented 3 years ago

Add a method to plot a mollweide projection of the spacing between distance bins (for the Bovy distances) for the sight-lines.

Motivation: all sight lines have the same number of distance bins but the L19 map max distances are a function of sight-line. This means the spacing between distance bins at which we evaluate Bovy et al., is a function of Galactic coordinates. Since the routines that query ebv currently find the nearest distance rather than interpolating along the lines of sight, it would be useful to know what if any impact the distance binning has on distance accuracy.

Implemented. See method ebv3d.showDistanceInterval() in module readExtinction.py.
