Photometry and Low Dispersion Spectroscopy with ESA Gaia

Figure 10

The simulated 1D low dispersion spectra by Gaia according to Bailer-Jones et al., 2008 [17]. The x-axis in pixels covers the BP and RP range, on y-axis is the intensity (arbitrary units). This picture shows that even for very low dispersion spectra without visible spectral lines valuable information can be obtained and scientifically used from the spectral continuum profile.
