HealpixSkyMapConfig

class lsst.skymap.healpixSkyMap.HealpixSkyMapConfig(*args, **kwargs)

Bases: BaseSkyMapConfig

Configuration for the HealpixSkyMap

Deprecated since version 28: HealpixSkyMapConfig has been deprecated and will be removed after v28.

Attributes Summary

log2NSide	Number of sides, expressed in powers of 2 (int, default 0)
nest	Use NEST ordering instead of RING? (bool, default False)
pixelScale	nominal pixel scale (arcsec/pixel) (float, default 0.333)
projection	one of the FITS WCS projection codes, such as:- STG: stereographic projection- MOL: Molleweide's projection- TAN: tangent-plane projection (str, default 'STG')
rotation	Rotation for WCS (deg) (float, default 0)
tractBuilder	Algorithm for creating patches within the tract.
tractOverlap	minimum overlap between adjacent sky tracts, on the sky (deg) (float, default 1.0)

Methods Summary

setDefaults()

Subclass hook for computing defaults.

nest

Use NEST ordering instead of RING? (bool, default False)

pixelScale

nominal pixel scale (arcsec/pixel) (float, default 0.333)

projection

one of the FITS WCS projection codes, such as:- STG: stereographic projection- MOL: Molleweide’s projection- TAN: tangent-plane projection (str, default 'STG')

rotation

Rotation for WCS (deg) (float, default 0)

tractBuilder

Algorithm for creating patches within the tract. (RegistryInstanceDict, default 'legacy')

tractOverlap

setDefaults()

Subclass hook for computing defaults.

Notes

Derived Config classes that must compute defaults rather than using the Field instances’s defaults should do so here. To correctly use inherited defaults, implementations of setDefaults must call their base class’s setDefaults.
