            SPoly

A spherical polygon from pgSphere.

The constructor accepts a list points of SPoints.

Method Details

init(self, points)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

asDALI(self)

source code

returns the DALI form of this polygon.

This is a sequence of floats of the vertex coordinates in degrees.

fromDALI(cls, daliSeq)
Class Method

source code

returns a polygon from a DALI float-sequence

This returns None for empty daliSeqs to help with VOTable NULL value handling.

asCooPairs(self)

source code

returns the vertices as a sequence of (long, lat) pairs in degrees.

This form is required by some functions from base.coords.

asPoly(self)

source code

Overrides: PgSAdapter.asPoly

asSMoc(self, order=6, inclusive=True)

source code

returns an SMoc instance for this polygon.

If inclusive is False, do not include healpixes that lie

order is the maximum order of the moc returned.
