The use of "FIXED_TARGETS" and "GENERIC_TARGETS" 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 Chapter 4: 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:
In this chapter, each heading has a description followed by a keyword in square brackets (e.g., [Number]). Elsewhere, items in boldface (e.g., RA) show words or phrases that are used as APT Phase II keywords or properties. Items in <> brackets (e.g., <value>) show values you provide. Values of items listed in square brackets (e.g., [A1: <value>]) are optional, whereas those not in square brackets are required. As you enter information in the APT interface
, you will be told (via a tooltips message) if an item is required.
