Differences in spectral slopes.

Observation	Δλ (nm)	S (%/100 nm)
9th/04–12h13	535–882	17.8 ± 2.2
α ~62°	535–743	21.6 ± 2.9
	535*–743	21.2 ± 2.6

10th/04–11h50	535–882	17.6 ± 2.3
α ~51°	535–743	21.0 ± 3.0
	535*–743	20.4 ± 2.6

Notes. Spectral slope values (S, center, and FWHM) of the Gaussian fitting for each spectral slope mapping considering their wavelength range (Δλ). The asteriskdenotes that the corresponding 535 mappings were interpolated from the associated 480 and 649 nm filter images.
