The following phase II has been updated and correctly selects "F850LP" in the appropriate exposures. Exposure lengths have been appropriately adjusted to account for this change. ----- Attempting Submission 2 (Wed Oct 12 17:49:33 GMT 2011) ----- The remaining diagnostics have been discussed with the program coordinator and are fine for our observations. DIRECT CHANDRA CONSTRAINTS ON THE EVOLUTION OF FIELD LMXB POPULATIONS We propose to study in detail the field LMXB populations in four nearby early-type galaxies that cover a broad range of mean stellar ages (3-10 Gyr). We will conduct deep Chandra observations of two galaxies with young and intermediate stellar ages (3-5 Gyr), and image with HST three of the four galaxies. These observations will allow for (1) the detection of >50-100 LMXBs per galaxy, (2) the separation of GC and field LMXBs, and (3) provide empirical constraints on how the field XLF depends on stellar age.
We will be mapping with ACS imaging the galaxy NGC 3384 in three orbits, with each orbit observing a different region of the galaxy. For each orbit, we will take three F850LP (with one 90 s and two 575 s) and two F475W (at 355s each) exposures. We anticipate guide star acquisition for each orbit will require 6 min and filter changes, camera setups, and readouts will require a total of 15.5 min (3 × 2.5 + 2 × 4) during the orbit. The short exposure, included to guard against possible saturation of the galactic nuclei, occurs at the beginning of each orbit to avoid the buffer dump penalty. Total on source integration is then 32.5 min per orbit. 12 false 0.0 0.0 false false false false SUPPORTED GALAXY LENTICULAR J2000 J2000 ACS/WFC Imaging No No F475W ACS/WFC Imaging No No F850LP POS-TARG DITHER 2.994 LINE false true 2 85.27 ACS-WFC-DITHER-LINE 1 false POS-TARG DITHER 2.994 LINE false true 3 85.27 ACS-WFC-DITHER-LINE 2 false Same orient constraint links visits (04 05 06) The scheduling data was generated by CASM 19.3.
