VizieR Online Data Catalog: K band spectrum of beta Pictoris b (GRAVITY+, 2020)
Abstract
The data consist of an absolute flux-calibrated spectrum of the giant planet beta Pic b in K band (1.97 to 2.49 microns). The data reduction procedure (see paper) gives the contrast spectrum (planet/star), which is then calibrated using a model spectrum of the star. The non-calibrated contrast spectrum is also given.
