VizieR Online Data Catalog: Spitzer/IRAC obs. of HD113766 & HD172555 systems (Su+, 2020)
Abstract
Multiple Infrared Array Camera (IRAC) 3.6 and 4.5um observations were obtained during the Spitzer warm mission, resulting in a total of 11 Astronomical Observation Requests (AORs) for HD 172555 from PID 90250 (PI: Stapelfeldt) and 11093 (PI: Su), and 67 AORs for HD113766 from PID 11093.
Both objects have two Spitzer visibility windows per year with each having a length of ~46-52 days. Various observation cadences were used to search for flux variability. A cadence of 10+/-2 days was used for HD 172555 under PID 11093 for both visibility windows in 2016, where the flux can be compared to the one obtained in 2013 under PID 90250. For HD 113766, 5+/2 and 15+/-2 days were used in individual visibility windows. (2 data files).- Publication:
