Use region searches instead of HTM IDs for DP02_04b #208

Closed dhirving closed 2 days ago

The latest version of client/server Butler now supports arbitrary region searches, instead of requiring users to manually figure out the HTM pixelization IDs. The examples of spatial searches in DP02_04b have been updated to use the POINT() syntax.

This one uses new functionality not available until weekly 33, and the new functionality is client/server only. (DirectButler will get this in a couple months.)

So this should NOT be merged until both:

The recommended image gets bumped to weekly 33 or newer.
The dp02 alias changes to point to client/server.

I imagine you'll want to workshop the text surrounding this quite a bit.

You can also now write things like

region = lsst.sphgeom.Circle(...)
datasetRefs = registry.queryDatasets("calexp",
                                     where="visit.region OVERLAPS my_region",
                                     my_region: region})

using any of the region types in lsst.sphgeom..
