Submission aborted. ----- Attempting Submission 5 (Mon Jul 03 08:08:54 GMT 2023) ----- All warnings are on minimum exposure times, and we do accept the rounding to 0.1s and/or a minimum exposure/readout time of 0.1s. Depending on the physical sizes of the coronagraphic occulters on STIS, they have imaged the surrounding environments of central bright sources down to ~0.2 arcsec. Recent understanding of the current ~7 mas pointing stability of HST can push beyond such a limit: by incrementally dithering along the perpendicular direction of the STIS occulters, and with carefully designed exposure times, we could image the surroundings of central sources down to 0.1 arcsec or less. We propose to perform such an instrumental calbiration exploration for the BAR5 and WedgeA0.6 occulters of STIS, and thus push the supported inner working angle (IWA) to one that supercedes the stated values. Using a total of 4 orbits on the prototypical debris ring around HR 4796A and its point spread function star, we expect to recover the minor axis of the ring at a radius of ~0.15 arcsec. Upon the completion of this program, we will provide STIS instrumental science report to establish formal guidelines in using this mode for future users. We use 4 orbits of STIS coronagraphic observations to explore the surrounding environments for HR 4796 A, a V = 5.774 debris disk host. In each orbit, we use a combination of both the BAR5 occulter and the WEDGEA0.6 occulter to achive our goal of pushing down the inner working angle (IWA) for the two occulting locations. There is one set of observations (V1 to V4) with 4 "back-to-back" orbits. a. Reference-point Orbit: In each set, we orient the telescope with respect to the 2nd visit (i.e., V2). The other two HR 4796 A visits are +/- 22.5 deg from V2 -- by doing so can we best reduce the impact of diffraction spikes in overwhelming the debris disk ring. b. Point Spread Function (PSF) Orbit: To capture the PSF of HR 4796 A, we use the 3rd visit (i.e., V3) to observe a nearby color-matching star, HR 4375, which has been used in GO-13786 as the reference star for HR 4786 A. In this way, we can ensure the usage of the same reference star, and thus the thermal settling of the telescope can be achieved after a slew (which happens usually within 1 orbit) and permit optimal PSF stability. c. Telescope Roll Range: To observe the minor axis of the HR 4796 A debris disk ring, the absolute orientation in V2 should be constrained within 320 deg to 359.99 deg (ideally, as has been identified in Phase 1 using the VISIT-STIS-Coron tool at https://github.com/seawander/VISIT-STIS-Coron), or 0 deg to 10 deg and other ORIENT values specified in V2 (if the ideal constraint cannot be ensured; obtained using VISIT-STIS-Coron as well). In this way, we can position the minor axis of the debris ring outside the coronagraphic masks, which is the primary goal of this proposal. Exposure Information: In each HR 4796 A or HR 4375 visit, we evenly distribute the observations to the BAR5 occulter and the WEDGEA0.6 occulter. a. Angular Coverage: the two occulters are nearly perpendicular to each other, so that we can probe the HR 4796 A surroundings with a nearly 360 deg angular coverage after 3 orbits. b. Readout Number: At each occulter location, we have three readouts with CR-SPLIT = 3 or more to permit cosmic ray rejection. By dithering between 2 and 4 STIS pixels from the orignal center, we aim to establish a smaller IWA for both BAR5 and WEDGEA0.6. The readout times are designed to be below HALF of the 80% potential well for STIS CCD, so that telescope jittering may not significantly induce saturation. PSF Star Selection: We use HR 4375 that has previously been used in GO-13786 as the reference star for HR 4796 A. The exposure times are correspondingly scaled to taked into account of the brightness between the PSF star and the science target (HR 4796 A). Impact of Reduced Gryo Mode (RGM): RGM 1. Field of regard: with an RA of 189.0 deg and Dec of -39.9 deg for HR 4796 A, and and RA of 186.7 deg and Dec of -32.8 deg for HR 4735, both of the target and the reference star are still accessible according to the 2019 May reduced-gyro mode presentations at https://www.stsci.edu/hst/about/space-telescope-users-committee/presentations-and-documentation . RGM therefore does not impact the observability of targets for GO-17135. RGM 2. Spacecraft orientation: while it is ideal if we have 4 "back-to-back" orbits with relatively loose ORIENT constraints, we can reach our original science goal if 3 "back-to-back" orbits with highly specified ORIENT constraints. Under the most pessimistic scenarios, we will schedule two separate sets of 2 "back-to-back" orbits to attempt our goal of pushing down the IWA for STIS coronagraphy. Our team has more than 100 orbits of experience on STIS coronagraphic imaging observations and corresponding data reduction. In addition to possessing the entire aligned STIS coronagraphic imaging archive for the proposed activity of point spread function (PSF) removal using multiple reference stars and multi-roll images of the science target, we have planned, scheduled, and reduced the corresponding data for STIS observaions. a. PSF modeling: Together with our collaborators, Debes and Ren lead studies in (1) aligning and assembling the STIS coronagraphic archive to allow for optimal PSF capture, (2) developing advanced statistics methods (e.g., non-negative matrix factorization, data imputation) to allow for optimal PSF modeling using the STIS coronagraphic archive. b. Morphology analysis: (1) Most of the investigators are experienced analyzers of coronagraphic observations with STIS and VLT/SPHERE from existing PI programs. (2) Together with our collaborators, Ren lead in the developing of an advanced method (dummy variable least square fitting) to capture motion of a system of components, reducing the uncertainties by a factor of ~10 than previous methods. c. Instrumental background: Debes and Ren characterized the high contrast imaging and dithering capability for the STIS BAR5 occulter, which allows for BAR5 coronagraphic imaging using this mode since 2016. d. Ground-based high-contrast imaging: Fogarty, Mawet, and Ren has been working on the technological verification and application of the Keck/NIRC2 capability using the Pyramid Wavefron Sensor that operates in near-infrared to probe structures down to ~0.1 arcsec. Ren has been supporting advanced data reduction on the VLT/SPHERE coronagraphic archive to not only extract circumstellar disk images in total intensity, but also directly image planets at close-in separations.
