CoaddUnits

class lsst.cell_coadds.CoaddUnits(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Enumeration of units a coadd’s pixels may have.

Notes

This list is intentionally limited to the units we know we need rather than units we think somewhat might want (which is also why we do not support any flux unit other than nJy).

Attributes Summary

chi	Pixels represent a signal-to-noise ratio.
legacy	Pixels in semi-arbitrary unit obtained by scaling the warps to a common zeropoint (typically 27).
nJy	Pixels represent flux in nanojanskies.

Attributes Documentation

chi = 3

Pixels represent a signal-to-noise ratio.

legacy = 1

Pixels in semi-arbitrary unit obtained by scaling the warps to a common zeropoint (typically 27).

nJy = 2
