Submission of Phase 2 file for PID 13743. Warnings about sensitive exposures and ETC run numbers remain, but I believe they can be ignored. -1281973205 ----- Attempting Submission 1 (Thu Jul 24 06:15:33 GMT 2014) ----- I get the warning 'Sensitive exposures should have an ETC run number provided.' Our phase one proposal has already justified the required amount of exposure per filter, which we essentially achieve in this Phase 2. I think these warnings can be ignored safely. The Controversial Nature of the Diffuse UV Emission in Galaxies: Exploring NGC300 The wealth of data produced over the past decade by sensitive IR and wide-field UV space facilities has ushered a new era for studies of star formation in galaxies, both at the whole-galaxy and sub-galactic (<~kpc) scale. These data underscore the difficulty of using standard methods, including the dust-corrected UV light, to measure star formation within galaxies, owing to the local variations in stellar population and dust properties. The UV should be a direct tracer of young stellar populations and recent star formation, yet UV colors in the 'diffuse' interarm regions of spiral galaxies are unusually red relative to those of spiral arms, even after accounting for dust attenuation. This suggests a complex mix of moderately aged stars and dust, plus perhaps scattered light. We will unveil the origin of those UV colors with new ACS far-UV (FUV) and WFC3 near-UV (NUV) images of the nearby, prototypical spiral NGC300, which will be combined with B,V,I archival images. By exploiting the dust-insensitivity of the HST FUV-NUV color for resolved stars, we will obtain a census of both O and B stars in order to: (1) uncover the nature of the UV-emitting interarm stellar populations, while estimate the true diffuse fraction; (2) constrain the extinction law in both interarm+arm regions; (3) place UV-based SFR indicators on a secure footing for use both at low and high redshift. The angular resolution and UV capabilities of HST are crucial for this project. By directly addressing the use and limitations of UV colors to trace young stellar populations and dust attenuation in galaxies, this project maximizes the return from the large investment of HST time devoted to high-z surveys. Our proposal aims at determining the nature of the red UV colors in the interarm regions of a prototype nearby spiral, NGC300, through differential comparison with the UV light in the arms. We will resolve and count individual O and early-to-mid B main sequence stars, and estimate the fraction of UV light these massive (current and recent SFR-associated) stars provide. This can be only accomplished with the UV capability and resolution of HST. We will then measure any excess UV light that may be associated with evolved (non recently formed) stellar populations, in order to establish the origin of the red UV colors. We will finally constrain the level of truly diffuse UV, as might originate from dust-scattered light, which is expected to vary with environment. To achieve these goals, we will combine new ACS/SBC FUV (F150LP) and WFC3/UVIS NUV (F218W+F225W) imaging with archival B, V, and I imaging, using photometry to determine stellar types and extinction-corrected luminosities. We will also obtain WFC3 NUV,U,B,V,I images in parallel with the SBC primaries, to maximize statistics, and probe significantly different disk areas. WFC3/UVIS primary observations have been planned in visit 01, whereas the ACS/SBC primary imaging and WFC3/UVIS parallel exposures have been planned in visits 02-05. The orient range of visit 01 is constrained to approximately match archival imaging being used for our program, but also more importantly insure that the primary SBC fields (visits 02-05) remain contained within the visit 01 WFC3 footprint. Although the WFC3 exposures could also be obtained with an orient 180d different, the choice of orient will facilitate an additional requirement described below regarding visit ordering. We have imposed 'AFTER VISIT 01 BY 7 to 360 DAYS' for visits 02-05 in order to allow inspection of the WFC3 NUV imaging for the primary target field prior to the expensive SBC observations. In this way we may slightly shift our SBC pointings (visits 02-05) based on the observed distribution of NUV-bright stars revealed in visit 01, for the sake of optimizing number statistics in this comparatively rare interarm population. The orient ranges specified for visits 02-05 have been selected to place the parallel WFC3 observations in areas of the NGC300 disk most relevant to our science goals, specifically sampling spiral and interarm regions but at significantly larger galactocentric radius than our primary field. Dithering is implemented for all primary observations using a WFC3-UVIS-DITHER-LINE-3PT pattern for the WFC3/UVIS imaging and a set of four POS_TARG offsets for the ACS/SBC imaging, designed to mimic standard pattern ACS-SBC-DITHER-BOX but allow parallel exposures to be obtained with the desired exposure times. To mitigate CTE, post-flash has been requested for all WFC3 exposures at wavelengths shorter than 4500 Ang (F218W, F225W, F336W, and F438W). We have used the GALEX FUV image (central wavelength ~1530A) to calculate the maximum global count rate within the SBC FoV. This corresponds to our pointing on the arm region, which has surface brightness mAB(FUV)=18.97 mag/arcsec2. The ACS/SBC ETC gives a global count rate of 600 c/s for this level, well below the Global Bright Object Limit. For the Local Bright Object Limit check, we have considered the brightest star we expect, an O3 star, at the distance of NGC300, without addition of any attenuation from dust. In this case, the ACS/SBC ETC returns a count rate of 9 c/s for the brightest pixel, again, well below the Local Bright Object Limit.
