VizieR Online Data Catalog: Hα interferometry obs. of the Be star 48 Per (Jones+, 2017)

Our observations of 48 Per were obtained at the Navy Precision Optical Interferometer (NPOI), located near Flagstaff, AZ, USA. Typically, observations from up to five unique baselines are obtained simultaneously; for this study, baseline lengths ranged from 18.9 to 64.4m. A total of 291 squared visibility measurements from a 150Å wide spectral channel containing the Hα emission line (i.e., centered at 6563Å) of 48 Per were obtained at NPOI in 2006 Nov 7-23.
