badMaskPlanes#

Mask planes that indicate pixels that should be excluded from the fit. (List, default ['BAD', 'SAT'])

deblendNChild#

Field name for number of deblend children. (str, default '')

doMeasure#

whether to run this plugin in single-object mode (bool, default True)

shearType#

Base class property for the desired method of PSF correction.

The following options are available through GalSim. The first three options return an e-type distortion, whereas the last option returns a g-type shear:

  • “REGAUSS”: Regaussianization method from Hirata & Seljak (2003).

  • “LINEAR”: A modification by Hirata & Seljak (2003) of methods in Bernstein & Jarvis (2002).

  • “BJ”: The method developed by Bernstein & Jarvis (2002).

  • “KSB”: The method from Kaiser, Squires, & Broadhurst (1995).

Subclasses can override this property, but it cannot be set externally, making it effectively read-only.
