Our observations will robustly test (to the 96.5-99.4% confidence level) theoretical population synthesis models, which predict a decline in field LMXBs with increasing age. Our survey will also contain detections for ~800 globular cluster (GC) LMXBs, dramatically improving constraints on whether GC LMXBs seed field LMXBs by being kicked out of their host GCs. To perform this experiment, we will leverage >4 Ms of Chandra exposures and >35 HST orbits for 9 galaxies that exist in the archive, and will add 255 ks of new Chandra time and two new HST orbits for two young early-type galaxies. ------------------------------------------------------------------------------------ Observations Description ------------------------ In this set of observations, we will be observing NGC 3585 in two unique observational fields with ACS in two bands: F475W and F850LP. These two observations will supplement existing archival data (in the same ACS bands) that cover the center of the galaxy. Our intention is to combine the two new fields with the existing archival field to create a mosaic of the galaxy. Therefore, our field choices are based on covering to the largest extent possible the entire D25 area of NCGC 3585 when considering the already covered archival area. ------------------------------------------------------------------------------------ 14852( 6) - 04-Oct-2016 17:42:10 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC3585-A GALAXY, ELLIPTICAL RA=11H13M21.2638S, J2000 V = 11.0 +/- 1.0 DEC=-26D45'39.04" Reference Frame: ICRS Extended: YES Comments: Coordinate location assumes center of the ACS field ------------------------------------------------------------------------------------------------------------------------------------ 2 NGC3585-B GALAXY, ELLIPTICAL RA=11H13M14.3027S, J2000 V = 11.0 +/- 1.0 DEC=-26D45'5.58" Reference Frame: ICRS Extended: YES Comments: Coordinate location assumes center of the ACS field ------------------------------------------------------------------------------------------------------------------------------------ 14852( 6) - 04-Oct-2016 17:42:10 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-LINE Pattern_Purpose DITHER Number_Of_Points 2 Point_Spacing 3.034 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 85.29 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 14852( 6) - 04-Oct-2016 17:42:10 - [ 4] Visit: 03 Visit Requirements: ORIENT 110D TO 115 D On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC3585-A ACS/WFC ACCUM WFC F850LP 1 394 S POS TARG 0, 0;
