242( 4) - 03/27/97 17:36 - [ 1] PROPOSAL FOR HUBBLE SPACE TELESCOPE OBSERVATIONS ST ScI Use Only ID: 242 Version: 4 Check-in Date: 27-Mar-1997 17:31:22 1.Proposal Title: Non-centerlined Acquisition Scenario for SNAP proposals ------------------------------------------------------------------------------------ 2. Scientific Category 3. Proposal For 4. Cycle SNAP 6 ------------------------------------------------------------------------------------ 5. Investigators Contact? PI: Andy Gerb SPACE TELESCOPE SCIENCE INSTITUTE ------------------------------------------------------------------------------------ 6. Abstract This proposal is intended as a copy of proposal 241 with the proposal category set to SNAP. Based on opr 31024, SNAPS have different acquisition scenarios as other proposals, so they need to be tested in a separate proposal. ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_Address Ship Via: UPS Email: ------------------------------------------------------------------------------------ 242( 4) - 03/27/97 17:36 - [ 2] TARGET LIST a) Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 FIXED STAR,BROWN DWARF RA=0.0000000D +/- J2000 V = 0.0+/-0.1 0.0001000D,DEC=0.0000000D +/- 0.0001000D 2 FIXED2 STAR,BROWN DWARF RA=0.001D +/- 0.0001D,DEC=0.0D J2000 V = 0.0+/-0.1 +/- 0.0001D 242( 4) - 03/27/97 17:36 - [ 3] TARGET LIST b)Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 3 | TARGET NAME: NEPTUNE ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: PLANET NEPTUNE ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 | TARGET POSITION LEVEL 2 | STD=NEPTUNE | | ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 | WINDOWS | | ------------------------------------------------------------------------------------------------------------------------------------ DATA | COMMENTS | V = 8.0+/-0.1 | | Ephemeris Uncertainty: 15 S | Acquisition Uncertainty: 15 " | ------------------------------------------------------------------------------------------------------------------------------------ 242( 4) - 03/27/97 17:36 - [ 4] Visit: 01 Visit Requirements: On Hold Comments: Additional Comments: This tests that a DITHER is treated as motion in the obset.
