Recipes ∞

SOXSPIPE borrows the informative concept of `recipes’ employed by ESO’s data reduction pipelines to define the modular components of the pipeline. These recipes can be strung together to create an end-to-end workflow that takes as input the raw and calibration frames from the instrument and telescope and processes them all the way through to fully reduced, calibrated, ESO Phase III compliant science products.

Dispersion and Spatial Solutions ∞

There is a strong curvature in the traces of the NIR orders and spectral-lines do not run perpendicular to the dispersion direction, but are highly tilted. Therefore wavelength cannot be expressed as simply a function of pixel position, but instead detector pixel positions (\(X, Y\)) much be mapped as a function of:

  1. wavelength \(\lambda\)

  2. order number \(n\), and

  3. slit position \(s\)

This 2D mapping function is determined incrementally via the soxs_disp_solution, soxs_order_centres and soxs_spatial_solution recipes. The soxs_straighten recipe can then be used to transform spectral images from detector pixel-space to wavelength and slit-position space
