PI: WILLIAM JEFFERYS UNIVERSITY OF TEXAS CoI: George F. Benedict UNIVERSITY OF TEXAS Y ------------------------------------------------------------------------------------ 6. Abstract We propose to obtain ST WF/PC surface photometry of NGC 7479. NGC 7479 exhibits anomalous nuclear activity indicative of on-going star formation. Multicolor surface photometry with 0.1 to 0.2 arcsec resolution will afford an opportunity to explore the global interrelationships between gas clouds, dust, star formation, and stellar populations with detail never before obtained. The expected maximum resolution for for NGC 7479 is 20 parsecs. All exposures will be secured with WFPC2. ------------------------------------------------------------------------------------ Observations Description ------------------------ Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: Benedict, McDonald Obs, UTEXAS, Austin, TX 78712 Ship Via: UPS Email: fritz@dorrit.as.utexas.edu , ------------------------------------------------------------------------------------ 6266( 0) - 07/18/95 21:39 - [ 2] TARGET LIST a) Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC7479 GALAXY,spiral, RA=23H 02M 26.0S +/- 0.5S, B1950.00 V = SURF(V) = 19.0 +/- 1.5 starburst DEC=+12D 03' 9.8" +/- 0.5" 2604.
