Introduction

In this chapter we describe the current status of STIS calibration and the plans for future calibration in Cycle 10. At the time this Handbook is being written, Cycle 9 calibration is nearly complete. Detailed planning for Cycle 10 calibration is complete, but the observations have not yet begun. Below we give a brief guide to the calibrations obtained during ground testing, the Servicing Mission Orbital Verification (SMOV), and Cycles 7, 8, and 9. Further information on calibration, including detailed descriptions of the proposals, can be found on the STIS web pages.
