0 Assigned ID: 5948 ----- Attempting Submission 1 (Mon Oct 28 21:30:08 GMT 2024) ----- This is the initial submission. The orient is essentially unconstrained, but we do specify the observations to occur before early Feb 2025. This could be relaxed a bit if needed for scheduling or any repeat due to possible guiding problems. -- Max Mutchler Relaxed orientation and date constraints to ease guide star issues. -- Chris Britt Edit 11/01/24 V Bajaj: Changed filters with approval from CS. Removed F350LP and lengthened other filters. Split from a single 6 orbit visit to 2 3-orbit visits. 28 Jan 2025: Added POS TARGs to visit 2 so they are not the same pointings as visit 1, based on review feedback. Now they have non-overlapping gap dithers which evens out the S/N near the galaxy core, and further mitgates any scattered light effects. -- Max Mutchler -1289484305 ----- Attempting Submission 1 (Thu Oct 31 15:29:01 GMT 2024) ----- ----- Attempting Submission 2 (Fri Nov 01 19:55:30 GMT 2024) ----- ----- Attempting Submission 3 (Thu Jan 02 16:50:46 GMT 2025) ----- ----- Attempting Submission 4 (Tue Jan 28 15:37:33 GMT 2025) ----- Broadband imaging of NGC 5335 We propose to take deep broadband imaging of the barred ring galaxy NGC 5335 in broadband filters F475W, F625W, and F814W, to highlight the ring and spiral structures and areas of recent star formation. We will obtain high signal-to-noise imaging of NGC 5335 in broadband filters F475W, F625W, and F814W. The BVI filters will provide color that highlights regions of newer star formation. Additionally, data from the three filters can be combined into a "white light image" which can be used to further accentuate the brightest regions. We propose a single WFC3 pointing which will adequately cover the entire object at any Position Angle. In the event of needing to retake a failed visit, we will attempt to match the PA; in the event that this is not possible to schedule in Reduced Gyro Mode, we will crop and zero-pad the image background as necessary so that no part of the image is missing one or more colors. Targets and dither strategies are selected to minimize the impact of variation of the PA. We will also employ a dither pattern which fills the chip gaps and enables cosmic ray rejection. Most of the color composite will derive from the varying stellar temperatures and obscuration from dust in different parts of the disk. With exposure times calculated from template spiral galaxies within the ETC and DSS magnitudes, we can achieve the high signal-to-noise desired with 6 orbits. The team has a wealth of experience in making outreach images for the Hubble Space Telescope and is responsible for creating Hubble images viewed by billions of people world-wide, includingthe 31st, 32nd, 33rd, and 34th anniversary images which together were viewed over 3 billion times. The team includes decades of experience in writing Hubble news releases, designing informal educational and outreach products based on Hubble data, as well as instrument expertise specializing in treatment of WFC3 data.
