class drizzlepac.wfc3Data.WFC3InputImage(filename=None, group=None)

Bases: drizzlepac.imageObject.imageObject

SEPARATOR = '_'

class drizzlepac.wfc3Data.WFC3UVISInputImage(filename=None, group=None)

Bases: drizzlepac.wfc3Data.WFC3InputImage

doUnitConversions()

getdarkcurrent(chip)

Return the dark current for the WFC3 UVIS detector. This value will be contained within an instrument specific keyword.

Returns :  

darkcurrent: float :

The dark current value with units of electrons.

setInstrumentParameters(instrpars)

This method overrides the superclass to set default values into the parameter dictionary, in case empty entries are provided.

class drizzlepac.wfc3Data.WFC3IRInputImage(filename=None, group=None)

Bases: drizzlepac.wfc3Data.WFC3InputImage

doUnitConversions()

WF3 IR data come out in electrons, and I imagine the photometry keywords will be calculated as such, so no image manipulation needs be done between native and electrons

getdarkcurrent()

Return the dark current for the WFC3/IR detector. This value will be contained within an instrument specific keyword.

Returns :  

darkcurrent: float :

The dark current value in units of electrons.

getdarkimg(chip)

Return an array representing the dark image for the detector.

Returns :  

dark: array :

Dark image array in the same shape as the input image with units of cps

getexptimeimg(chip)

Return an array representing the exposure time per pixel for the detector.

Returns :  

dark: array :

Exposure time array in the same shape as the input image

setInstrumentParameters(instrpars)

This method overrides the superclass to set default values into the parameter dictionary, in case empty entries are provided.
