PI: Dr. Henry Kobulnicky University of Wyoming ------------------------------------------------------------------------------------ 6. Abstract See original (APT crapped out and won't load my old .apt files) ------------------------------------------------------------------------------------ Observations Description ------------------------ WFPC2 UBVI imaging of Westerlund 2 Galactic cluster. Two positions in order to encompass the entire region. One position places Westerlund 2 on the WF3 chip and one pointing places Westerlund 2 on the PC1 chip. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- 3-point line dither pattern is used, with 1/3 pixel spacing. The standard 4- point box dither pattern did not fit well into the orbit time. ------------------------------------------------------------------------------------ 10276( 2) - 05/12/04 15:58 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 WESTERLUND2 STELLAR CLUSTER, OB RA=10H24M1.1S +/- 0.1", DEC=- J2000 V = 12.0 ASSOCIATION, OPEN 57D45'30.0" +/- 0.1", PLATE- CLUSTER ID=0686 Coordinate Source: GSC_SURVEY_PLATE 10276( 2) - 05/12/04 15:58 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFPC2-LINE Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.329 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 45.0 Angle_Between_Sides Center_Pattern NO Pattern_Comments: There was not enough time to execute the standard box pattern, so 3 points will have to suffice. Please check that the parameters for this 3 pointed dither are the recommended ones. ------------------------------------------------------------------------------------------------------------------------------------ 10276( 2) - 05/12/04 15:58 - [ 4] Visit: 10 Visit Priority: Visit Requirements: PCS MODE FINE;
