The use of the RPS2 ÒFIXED_TARGETSÓ and ÒGENERIC_TARGETSÓ blocks are described in this chapter. To make the presentation of this material more concise, the section on solar system targets has been made into a separate chapter; see Chapter4:Solar System Targets List [Solar_System_Targets].

 

The Target List tells us where you wish to point HST and so must be filled out with care, precision, and accuracy. The Target List also provides the information that defines and describe the targets, and which was used to determine exposure times. Three different kinds of Target Lists exist for the following three classes of targets, but only the Target List(s) required for your proposal need be submitted:

• Fixed targets (all targets outside the solar system whose positions can be defined by specific celestial coordinates);
• Solar-system targets (all moving targets);
• Generic targets (targets defined by certain properties, rather than by specific coordinates).

In this chapter, each heading has a description followed by a keyword in square brackets (e.g., Target_Number). The keyword must be used in your RPS2 form. Elsewhere, items in boldface (e.g., RA-OFF) show words or phrases that are to be used directly as RPS2 entries. Items in brackets (e.g., <value>) show entries you are to provide. Parameters listed in square brackets (e.g., [A1 = <value>]) are optional, whereas those not in square brackets are required.
