wavelength calibrated spectra

Forums Spectroscopy Spectrum of Nova Cas 2021 wavelength calibrated spectra

Robin Leadbeater

I just checked mine and Hugh’s spectra from 23rd March in the Nova Cas 2021 thread. The graphed spectra are calibrated in wavelength with a linear X axis and the Balmer (and other line) wavelengths are correct and consistent between the two spectra



Mike’s spectrum image is not calibrated in wavelength.


Prism spectra are very non linear with the short wavelength end significantly stretched and the longer wavelengths compressed
