Cycle 1 Calibration Programs

To ensure the calibration of all science instruments and observing modes, the Cycle 1 Calibration plan has been designed to focus on the observations planned for Cycle 1. The plan includes the data and methods necessary to:

  • Test and improve all calibration files used by the data reduction pipeline
  • Establish baselines for future comparisons
  • Monitor the health, responsivity, and throughput of the telescope and science instruments for any temporal changes

It is important to remember that the Cycle 1 Calibration plan is not final. When the General Observer programs for Cycle 1 have been determined, the calibration plan will be re-assessed to ensure that the calibrations are appropriate based on the approved programs. Commissioning may also lead to revisions in the calibration plan. For these reasons, the plan as laid out here should not be interpreted as a guarantee that any single observation will be obtained. Rather, it is our best estimate of what will happen in Cycle 1 based on what we know now (as of March 2020).

The information below provide details for the four science instruments, the Fine Guidance Sensor (FGS), and the absolute flux calibration plan (a multi-instrument plan that is treated as its own integrated program). Each entry provides the program ID, title, and abstract of each Cycle 1 calibration activity, as well as a link to the STScI Program Information tool, which provides access to the APT file. The APT files can also be accessed directly within the APT by querying the program ID. To view the details of a specific program, expand a category below and then click the ID number for the program.
