Flux calibration

[Kevin Gurney]

I  recently tried flux calibration of an Alpy spectrum using David
 Boyd’s method. I had acquired my own photometry for the target with a
 view to bring the two data sets together in this way…

I started to read a bit more about flux and magnitudes etc and
disappeared down a rabbit hole… 🙂 Flux can be a counting concept
(photons, electrons, ADU) or energy-based. The relation between the
two is given by the Planck–Einstein relation (E = h c / lambda) and so
they are not directly comparable….

However, in obtaining the instrument response using a MILES star, it seems we come good in the end.

I attach a brief analysis that I hope sheds some light!
