About this image

This is the spectrum for a Miles comparison star HD181096 (taken as a standard for observations on WZ Lyr) and the spectrum from the Miles database itself both of which have been flux calibrated using a Simbad V filter value of 6.0.

There's generally good agreement from 380nm up to about 620nm but there's a divergence thereafter the reasons for which could be due to either an error in the camera response curve or perhaps the star's mag in the R band at 5.7 (and I band at 5.5). That is, it's actually dimmer in that regime but I haven't been able to accommodate a second value in my comparison. (That last bit is just thinking aloud).
