FITS Data Analyzer
Drag&Drop or load FITS datafile to show spectrum.
Keyboard Controls
- right/left arrow keys move spectrum
- +/- key spreads/narrows spectrum
- up/down arrow keys spreads/narrows spectrum in flux
- Click and "v" calculates Doppler-velocity considering closest spectral line
- Click and "c" calibrates whole spectrum to closest spectral line, e.g. compensates Doppler effect
- Click and "n" opens NIST Databank search around clicked wavelength +/- 0.01 nm (calibrate spectrum first!)
- Click and "m" measures distances between points
