Cycle 20 Phase II Proposal Instructions |
Each target in your program will be assigned its own unique number by APT (they are base 10 and go from 1 to 999). A different target must be defined whenever different coordinates or a different target description are required. Separate targets should be defined and listed if you plan to take observations at several points within an extended object. For example, if you were to take spectra at three different locations in the Crab Nebula, each point must have its own target number, name, and coordinates, such as CRAB1, CRAB2, and CRAB3.If you are using the Text Proposal File, all target numbers and names within a proposal must be unique.
