5.3 Visit-level Special Requirements
[Visit_Requirements]

A variety of visit-level Special Requirements may be chosen; these requirements apply to all exposures in the visit (exposure-level Special Requirements are discussed in Chapter 7, Special Requirements [Visit and Exposure Special_Requirements]). These requirements will be interpreted by the computer software that is used to schedule the observations; therefore it is essential that the specific formats shown in Chapter 7, Special Requirements [Visit and Exposure Special_Requirements] are followed precisely. If none of the allowed Special Requirements appears to be sufficient, you can describe the requirements with a text explanation in Visit_Comments. You should contact your Program Coordinator prior to entering such a comment in your proposal.

Several of these Special Requirements require the use of limited resources or may impose serious constraints on the scheduling system (e.g., ORIENT, CVZ, BETWEEN). Use these Special Requirements with care.

The visit-level Special Requirements are described in detail in Chapter 7, Special Requirements [Visit and Exposure Special_Requirements].

Text Proposal File

If you are using a Text Proposal File to modify your program, please be aware that only the shortest form of the special requirements will be accepted when you import your template back into APT (e.g., use ORIENT <angle1> TO <angle2>). Also, new lines will not be sufficient delimiters for a list of special requirements. You must use semicolons to separate special requirements items.
