In-flight calibration of the stray-light blocking efficiency of HST/ACS Stray-light contamination is the most critical component of the sky background in optical and near-infrared images obtained with HST. Its presence in science images generates unwanted background artifacts, reducing their scientific impact and erasing the dim signal from astronomical sources. Currently, there is no methodology to predict, model, or correct the stray-light background in Hubble images due to the lack of precise measurements of the stray-light blocking efficiency of the observatory, described through a function called Normalized Detector Irradiance (NDI). The diffuse emission in the outskirts of galaxies such as stellar tidal streams, intracluster light (ICL), or the low surface brightness galaxies provides crucial evidence for the cosmological evolution of the Universe. However, these extended, low surface brightness (LSB) features are thousands of times dimmer than the sky background (SB = 29-30 AB mag arcsec-2, at 0.7 um) and very sensitive to the presence of gradients of stray-light. Unveiling this informative, yet hidden, emission with the Hubble Space Telescope thus requires an exquisite control and correction of large scale background gradients in the images. The goal of this proposal is to measure the stray-light blocking efficiency (NDI) of HST by obtaining a series of calibration exposures near extremely bright objects (Jupiter and the Moon). The proposed observations will enable to create models of the stray-light from out-of-field stars around the HST/ACS detector, allowing for the first time to correct artificial gradients in Archival HST imaging products, generating pixel-by-pixel stray-light models from bright stars for each observation. The observing plan of our program 17921: In-flight calibration of the stray-light blocking efficiency of HST/ACS consists of several observations at a certain distances from the Moon and Jupiter. The main objective is to measure the stray-light from extremely bright sources with ACS/WFC pointing the telescope up to 20 degrees away from the source. Our proposal is compliant within Moon avoidance distance and RGM considerations. In particular, the observations require us to point HST to any location at X degrees from the Moon (10, 15, 20 degrees) or Jupiter (at 0.05, 0.1, 0.5, and 1 degrees, no tracking of Solar System moving objects is required). The selection of these locations is flexible, any location on a 360 degrees around the targets would be acceptable. However, the relative position angle between the spacecraft axes and the source must be ~0, 30 and 60 degrees. All the orbits can be scheduled independently, although they should be obtained as close to the full phase of the Moon and Jupiter as possible. We shall avoid other bright sources, like bright stars or other planets. Dr. Alejandro S. Borlaff (PI), is responsible for all tasks related to software development for the image reduction and analysis, the estimation of stray-light in the exposures and the generation of the Normalized Detector Irradiance model. He is currently a research scientist a NASA Ames Research Center and an expert in image analysis and photometry methods. His experience in the use of state-of-the-art algorithms to recover low surface brightness emission from optical and near-infrared data (HST, Euclid, Roman) are critical to the success of this project. Dr. Pamela M Marcum, (co-I), provides overall management and leads tasks related to the photometry of the calibration sources - Moon and Jupiter - based on the solar spectra, phase, and albedo. She is currently a research scientist at NASA Ames Research Center and an expert in image analysis and photometry methods. As a former Program Scientist (Kepler, WISE) and Project Scientist (SOFIA), she has considerable experience in science management. Her experience in the study of extended extragalactic sources in astronomical images is strongly relevant to the goals of the proposed project. Dr. Scott Rohrbach, coll, is an Optical Systems Engineer at NASA's Goddard Space Flight Center. Dr. Rohrbach is an expert on the simulation of stray-light for space telescopes, with extensive experience in JWST and Roman. He is currently working at part of the Roman Space Telescope team, and he will provide assistance with the analysis of the stray-light surface brightness on the proposed HST/ACS observations. In addition, he will be responsible of comparing ray-tracing simulations used to reproduce the normalized detector irradiance (NDI) on space telescopes, with the results obtained from the proposed observations of the Moon and Jupiter. As required by the HST Calibration-GO proposals, the proposal team has contacted the ACS Instrument team (STScI Help Desk) and received their approval regarding the proposal calibration strategy.
