Purpose
This page is intended to collect all relevant observations of 3C273 performed under the coordinated IACHEC calibration program. We want to collect observation information (e.g., dates, exposure times, modes, etc.) as well as the extracted data by the instrument teams. The data will be available for use by any calibration team within the IACHEC consortium to perform instrument calibration.
Common GTIs
While most observations have a significant overlap, the start and stop times between the different missions do not align. We aim to provide a set of common GTIs that should be used for all instruments to select on the most useful overlapping time range. Data should be provided for the whole observation for each instrument, as well as the one filtered for the common GTI.
