3.1.7. addVAR
Add variance extension to MAROON-X frames.
Calculate the variance based on the read noise for the chip and the poisson noise (the variance in this case is just the number of photons for each pixel). The variance is then stored as a FITS extension for each file.
3.1.7.1. Parameters
- adinputslist of
AstroData List of MX objects without variance extensions.
- suffixstr
Suffix to be added to output files.
- read_noisebool
Whether to include read noise in variance calculations.
- poisson_noisebool
Whether to include poisson noise in variance calculations.
3.1.7.2. Returns
- list of
AstroData List of MX objects with variance extensions.
3.1.7.3. Parameter defaults and options
suffix '' Filename suffix
read_noise True Include read noise in variance
poisson_noise True Include poisson noise in variance
