PI: Dr. Alejandro Serrano Borlaff NASA Ames Research Center Y CoI: Dr. Pamela M Marcum NASA Ames Research Center N CoI: Dr. Scott Owens Rohrbach NASA Goddard Space Flight Center N ------------------------------------------------------------------------------------ Abstract 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. ------------------------------------------------------------------------------------ Observations Description ------------------------ 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 17921( 40) - 16-Sep-2025 19:03:57 - [ 2] 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. ------------------------------------------------------------------------------------ 17921( 40) - 16-Sep-2025 19:03:57 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 8 OFFSET-MOON- SOLAR SYSTEM, OFFSET RA=19H27M43.0121S, J2000 V = 17.5 10DEG-FIXED DEC=-16D52'44.27" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 9 OFFSET-MOON- SOLAR SYSTEM, OFFSET RA=19H31M7.4254S, J2000 V = 17.5 15DEG-FIXED DEC=-11D46'49.92" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 11 OFFSET-MOON- SOLAR SYSTEM, OFFSET RA=00H49M15.0720S, J2000 V = 17.5 15DEG-FIXED- DEC=+22D49'6.24" REPEAT Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 10 OFFSET-MOON- SOLAR SYSTEM, OFFSET RA=19H34M55.4383S, J2000 V = 17.5 20DEG-FIXED DEC=-06D30'19.89" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 17921( 40) - 16-Sep-2025 19:03:57 - [ 4] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: JUPITER-SCAN ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: OFFSET Mosaic including Jupiter up to 0.05 degree from FOV ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 STD=JUPITER ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS NOT ECL P PARTIAL OF JUPITER-SCAN BY IO FROM EARTH, NOT ECL P PARTIAL OF JUPITER-SCAN BY EUROPA FROM EARTH, NOT ECL P PARTIAL OF JUPITER-SCAN BY GANYMEDE FROM EARTH, NOT ECL P PARTIAL OF JUPITER-SCAN BY CALLISTO FROM EARTH, SEP OF JUPITER-SCAN MOON FROM EARTH GT 20D, SEP OF JUPITER-SCAN VENUS FROM EARTH GT 20D, PHASE OF JUPITER FROM EARTH BETWEEN 0 30, NOT GALACTIC LATITUDE OF JUPITER-SCAN FROM EARTH BETWEEN -23 23 ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = -2.4 +/- 0.5 Mosaic including Jupiter up to 0.05 degree from FOV Ephemeris Center: EARTH Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 17921( 40) - 16-Sep-2025 19:03:57 - [ 5] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 2 TARGET NAME: OFFSET-JUPITER-01DEG ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: OFFSET Jupiter at 0.1 degree from FOV ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 STD=JUPITER TYPE=POS_ANGLE, RAD=360, ANG=0, REF=NORTH ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS NOT OCC OF OFFSET-JUPITER-01DEG BY JUPITER FROM EARTH, NOT ECL P PARTIAL OF OFFSET-JUPITER-01DEG BY IO FROM EARTH, NOT ECL P PARTIAL OF OFFSET-JUPITER-01DEG BY EUROPA FROM EARTH, NOT ECL P PARTIAL OF OFFSET-JUPITER-01DEG BY GANYMEDE FROM EARTH, NOT ECL P PARTIAL OF OFFSET-JUPITER-01DEG BY CALLISTO FROM EARTH, SEP OF OFFSET-JUPITER-01DEG MOON FROM EARTH GT 20D, SEP OF OFFSET-JUPITER-01DEG VENUS FROM EARTH GT 20D, PHASE OF JUPITER FROM EARTH BETWEEN 0 30, NOT GALACTIC LATITUDE OF OFFSET-JUPITER-01DEG FROM EARTH BETWEEN -23 23 ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = 17.5 +/- 2 Any location at 0.1 degrees from the Jupiter.
