Phase 2 Proposal Instructions for Cycle 10

9.1 Introduction to WFPC2

---

The Instrument Configurations and Operating Modes described in the following section are used to specify exposures on the RPS2 Visit and Exposure Specifications. The legal Visit and Exposure Specifications entries are summarized in the following sections. More complete descriptions of Instrument Configurations, Modes, Apertures, Spectral Elements, Detector Characteristics, etc. are available in the WFPC2 Instrument Handbook.

Note that many of the Optional Parameters have default values; in such cases, an entry for an Optional Parameter in the Visit and Exposure Specifications is necessary only if it is desired to override the default value. The physical units of Optional Parameter quantities are always implicit and should never be entered by the observer.

Optional Parameters whose descriptions begin with the phrase ̉USE WITH CAUTIONÓ pose a risk to the intended science if a non-default value is used inappropriately. These parameters are italicized in Table 9.1. You may wish to discuss the use of these parameters with your Contact Scientist.

The following table lists the permitted Instrument Configurations, Operating Modes, Field of View, Spectral Elements, and Optional Parameters for the WFPC2.
