Jump in continuum at 5800A

[ymamay]

There is a distinct jump in the continuum around 5800Ang. This is present is all/most spectra (when looking at the median flux spectra from the CFrame for Sci, SkyE and SkyW). I have attached a plot showing an example of a single median spectrum of the flux from a Sci exposure and the median of the all the median spectra.

Some relevant investigation is available in this notebook.

Each point on this plot corresponds to an individual exposure. It shows that the majority of exposures, indeed, exhibit a jump at 5800A.

The image below illustrates the definition of spectral range used to calculate metric shown at plot above.
