API reference#
The full public API is re-exported from the top-level package, so everything
documented here is reachable as skyplothelper.<name> (conventionally
sph.<name>). The reference is grouped by subsystem; each page lists its public
functions and classes with auto-generated signatures from the source.

Frame conversions, sexagesimal helpers, angular distances, wrapping utilities.
Header coordinate grids, pixel/sky conversions, beam parameters, diagnostics.
RA/Dec tick formatters, offset ticks, VLBI hybrid labels, curved lon ticks.
Planes, survey footprints, constellations, beams, rulers, reticles, annotations.
Clip / stretch / normalize, quicklook figures, reprojection.
