Description
- Class:
- Alias:
white_light
Overview
The white_light step sums the spectroscopic flux over all
wavelengths in each integration of a multi-integration extracted
spectrum product to produce an integrated (“white”) flux as a
function of time for the target. This is to be applied to the _x1dints
product in a spectroscopic Time-Series Observation (TSO), as part of
the calwebb_tso3 pipeline. Minimum and maximum
wavelengths may be provided to limit the summation to specified
wavelength bounds, with limits inclusive.
Inputs
- Data model:
- File suffix:
_x1dints
The input should be in the form of an _x1dints product, which contains
extracted spectra from multiple integrations for a given target.
Algorithm
The algorithm performs a simple sum of the flux values over all
wavelengths for each extracted spectrum contained in the input product.
If provided, min_wavelength and max_wavelength will modify the
bounds of the sum to the specified bounds (see Step Arguments). For NIRISS SOSS data, if the
min_wavelength and max_wavelength are not provided, a wavelength
range appropriate to each filter and spectral order will be used; these
are read from the WAVELENGTHRANGE Reference File.
Outputs
The output product is a table of time vs. integrated flux values, stored
in the form of a ECSV Format file.
The product type suffix is _whtlt.
