The large volume of survey data gotten by the SDSS team became the cultural legacy. •30%-65% of X-ray afterglows of Swift-detected GRBs would be recovered by the follow-up campaigns of these neutrinos •A paper in preparation with upper limits considering more source scenarios: blazarsand supernovae •Plan to continue Swiftfollow-up observations of IceCube high-energy neutrinos at a rate of roughly four campaigns per year. Swift Response: My view Have a default X-ray/UVOT observing sequence Helps the community plan followup Uniform data sets will be one of the legacies of Swift Exceptions to be made for exceptional bursts Announce these via GCN. title = "The calibration of the Swift UVOT optical observations: A recipe for photometry", abstract = "The Ultraviolet/Optical Telescope (UVOT) on board Swift has the capability to provide critical insight into the physics of the early afterglows of gamma-ray bursts (GRBs). Swift/UVOT images have been calibrated using standard recipes39 and are reported on the AB system40. The UVOT provides a sub-arcsecond position and provides optical and ultra-violet photometry through lenticular filters and low resolution spectra (170-650 nm) through the use of its optical and UV grisms. Multiple filters covering λλ1,800-6,000˚A reveal a red source with spectral slope steeper than the 1. The Andromeda portrait is a mosaic of 330 images acquired between May 25 and July 26, 2008, for a total exposure time of 24 hours, by Swift's Ultraviolet/Optical Telescope (UVOT). First release of AB magnitude system for UVOT SWIFT UVOT CALDB RELEASE NOTE SWIFT-UVOT-CALDB-16-R01: AB magnitude system 1. regime that Swift covers, Swift is the first mission to cover the near-UV part of the spectrum. Marshall and the Swift Team NASA Goddard Space Flight Center, Greenbelt, Maryland, 20771, USA Abstract. 2004) and is co-aligned with the imately the same wavelength range and containing similar broad- 15-150 keV Burst Alert Telescope (BAT; Barthelmy et al. 4 UVOT Observation and Analysis The Swift/UVOT began settled observations of the field of GRB 100901A 147 s after the BAT trigger (GCN 11176). UVOT Operation. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in. The Swift Ultraviolet and Optical Telescope (UVOT) (Roming et al. The photosensitive surface is an S20 photo-cathode at the front of the detector with an active area of 19mm2.

Petersburg September 2014 • Wide field gamma-ray imager detects and finds position of GRB - BAT • On-board decision making – Spacecraft slews autonomously • Rapid slewing capability – Get to GRB quickly, sometimes while the prompt emission is still occurring. As described in Roming et al. The Swift Ultraviolet and Optical Telescope (UVOT) (Roming et al. Kuin (UCL-MSSL) and P. Swift image of asteroid (596) Scheila Faint dust plumes bookend asteroid (596) Scheila, which is overexposed in this composite image. Magnitudes and 3-sigma upper limits using the UVOT photometric system (Poole et al. Swift has detected an average of about 90 GRBs a year since its launch in 2004. LaPorte (PSU) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 190114A 258 s after the BAT trigger (LaPorte et al. UVOTSSC was compiled from 23059 Swift datasets taken within the first 5 years of observations with the Swift UVOT (between 10th Jan 2005 and 1st Oct 2010). Visible and ultraviolet images from Swift's UVOT (circled) are merged with a Digital Sky Survey image of the same region. Gamma Ray Bursts in the Swift Era Dick Willingale –St. It is expected that Swift will observe around 100 GRBs in a year. 2008, MNRAS, 383, p627 for details). at high count rates 38. The result is this gorgeous image. Holland (GSFC), M. We present the photometric calibration of the Swift Ultraviolet/Optical Telescope (UVOT) which includes: optimum photometric and background apertures, effective area curves, colour transformations, conversion factors for count rates to flux and the photometric zero-points (which are accurate to better than 4 per cent) for each of the seven UVOT broad-band filters. In Section 2,. As with the XRT, once the BAT detects a gamma-ray burst (GRB), the spacecraft slews to bring the new GRB into the UVOT's field-of-view. We also examined the data obtained using the the Swift/XRT and found that our source was undetected in the X-rays. SWIFT UVOT CALDB RELEASE NOTE SWIFT-UVOT-CALDB-104: POINT SPREAD FUNCTION Summary: This product provides the curve of growth (COG) of the UVOT Point Spread Function (PSF) for the 7 broad-band filters, V, B, U, UVW1, UVM2, UVW2 and White. Home > Data Analysis > UVOT UVOT Data Analysis UVOT analysis threads. Radius is an optional parameter and the default is 0. The Swift Green Filters SGF-ZS48 Replacement Refrigerator Filter, SubZero 4204490 compatible, is an environmentally friendly replacement cartridge. Logarithmic intensity scaling is used and the image is 5 arcmin on a side, with North up and East to the left. The complete suite of Swift instruments is necessary for optimal science analysis. The photometric calibration was performed following standard recipes 39 , and the reported. The SGF-ZS48 works in PRO 48 Refrigerators. NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Fluxes and uncertainties are in erg cm -2 s -1 A -1. 5 arcseconds. UVOT (~ 200 s) − Include postage stamp images from the three instruments − Optical finding chart from UVOT − Detailed data products available within 30 minutes of Malindi dump − Archive sites in US (HEASARC), Italy, and UK − Follow-up program coordinated by Kevin Hurley Swift Data Dissemination Everything to Everyone, Immediately!. 6, and 260 nanometers. In addition, the BAT's position is fed to the Swift spacecraft so a slew can be performed, bringing the GRB into the XRT and UVOT's fields-of-view. Within about 60 seconds of a burst trigger, the XRT refines the BAT position.
