calculate_uncertainty

irispy.utils.calculate_uncertainty(

data: ndarray,

readout_noise: astropy.units.Quantity,

unit: astropy.units.Quantity,

) → float

Calculates the uncertainty of a given data array.

Parameters:

• data (numpy.ndarray) – The data array.

• readout_noise (astropy.units.Quantity) – The readout noise, needs to be a unit that is convertible to photon.

• unit (astropy.units.Quantity) – The final unit that the value should be converted to.

Returns:

The readout noise with no unit.

Return type:

float
