JWST Cycle 1 Calibration Programs

The JWST Cycle 1 Calibration plan will ensure the calibration of all science instruments and observing modes.  This documentation focuses on the observations planned for Cycle 1 to support that effort.  The plan presented here includes the data and methods necessary to (1) test and improve all calibration files used by the data reduction pipeline (2) establish baselines for future comparisons and (3) monitor the health, responsivity, and throughput of the telescope and science instruments for any temporal changes.

When the Guest Observer program for Cycle 1 has been determined, the calibration plan will be re-assessed to ensure that the calibrations are appropriate to the accepted science programs and their objectives.  The results from Commissioning may also lead to revisions in the calibration plan.  For all of 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.

The links below provide details for the five science instruments, a category that includes the Fine Guidance Sensor (FGS), as well as the absolute flux calibration plan, which is a multi-instrument plan that is treated as its own integrated program.  Each linked page provides the title, program ID, and abstract of each Cycle 1 calibration activity, as well as a link to the STScI program page, which provides access to the APT file.  The APT files can also be accessed directly within the APT by querying the program ID.
