2010 HST Calibration Workshop
John Mather (NASA GSFC)
The James Webb Space Telescope is now in the construction phase, having passed its Mission Critical Design Review in April 2010. I will review the key scientific objectives that were used to set the engineering parameters, and I will describe the ...

Matthew Greenhouse (NASA GSFC)
The Integrated Science Instrument Module (ISIM) of the James Webb Space Telescope (JWST) is discussed from a systems perspective with emphasis on development status and element-level I&T plans. The ISIM is one of three elements that comprise the J ...
2010 HST Calibration Workshop
Robert Jedrzejewski (STScI)
The JWST Mission will, like HST, have a dedicated Calibration Pipeline that will be used to calibrate all science data from the observatory. Rather than follow the HST model of creating separate calibration pipeline programs for each Science Instru ...
2010 HST Calibration Workshop
Karl Gordon, Ralph Bohlin (STScI)
The planning for the absolute flux calibration of all four JWST science instruments will be described. The main goal is to provide a uniform calibration (photometric and spectrophotometric) across all instruments using a common set of calibration sta ...

Theodore Nakos (University of Ghent)
We present a list of 32 stellar sources selected for the in-orbit calibration/characterisation of the Relative Spectral Response Function (RSRF) of the Medium Resolution Spectrometer (MRS) of the Mid-InfraRed Instrument (MIRI) onboard the James W ...

Tracy Beck (STScI)
The Space Telescope Science Institute will serve as the main Science and Operations Center for the James Webb Space Telescope, which is a segmented 6.5m telescope that will operate in deep space at L2. There are some telescope characteristics that ...
2010 HST Calibration Workshop
Andy Fruchter (STScI)
We describe new developments in MultiDrizzle intended to allow users to easily and accurately align and combine HST images taken at multiple epochs, and even with different instruments. In the first part of this program, the correction of the time ...

2010 HST Calibration Workshop
Robert O'Connell  (University of Virginia)
I will describe some of the new scientific capabilities enabled by the extended wavelength coverage (0.2-1.7um), large suite of specialized filters, and improved "discovery efficiency" of HST's Wide Field Camera 3. Some examples from Cycle 17 program ...
2010 HST Calibration Workshop
John Mackenty (Space Telescope Science Institute)
The Wide Field Camera 3 was installed in HST in May 2009 during SM4. Designed to provide a factor of 10 or better increase in the near-ultraviolet and near-infrared imaging capabilities of the observatory, WFC3 has surpassed these expectations by lar ...
2010 HST Calibration Workshop
Jason Kalirai (STScI)
We characterize the total system throughput of HST/WFC3 by imaging both hot and cool HST spectrophotometric standard stars with both the UVIS and IR cameras. For the UVIS channel, our measurements indicate that efficiencies are higher than ground tes ...
2010 HST Calibration Workshop
Elena Sabbi (STScI)
Flat fielding is a standard calibration of step for astronomical data, which allows us to correct for variations in the local response of a detector and improve the accuracy of photometric analysis. As for ACS, ground based flat-fields (Sabbi et al., ...

Michael Wong (UC Berkeley)
2010 HST Calibration Workshop
Nor Pirzkal (STScI)
The near infrared background, as seen using the WFC3 IR channel, varies by several orders of magnitude. Ever since WFC3 was installed on HST, we have been monitoring and examining incoming observations of sparse fields. This monitoring has enabled u ...

Harald Kuntschner (ESO/ST-ECF)
2010 HST Calibration Workshop
Bryan Hilbert (STScI)
Using data taken during Servicing Mission Observatory Verification (SMOV4) and Cycle 17, we have characterized many aspects of the on-orbit behavior of the IR Channel. We find the dark current in the IR channel to be 0.043 - 0.050 e-/s/pixel. The ...
2010 HST Calibration Workshop
Knox Long (STScI)
As is the case for most if not all modern IR arrays, bright sources observed with the IR detector in WFC3 leave faint residual images in subsequent exposures. Persistence has been observed not only in dithered exposures by one observer of a single t ...
2010 HST Calibration Workshop
Adam Riess (Space Telescope Science Institute)
Previous HgCdTe detectors on HST have suffered from a count-rate dependent non-linearity, motivating an investigation of a similar effect on the WFC3-IR detector. An initial measurement of this effect was made by comparing the photometry of star clus ...
2010 HST Calibration Workshop
Howard Bushouse (STScI)
Standard WFC3 image processing consists of the calwf3 task, which removes instrumental signatures from the images, and multidrizzle, which corrects images for geometric distortion and combines dithered sets of exposures. The status and future plan ...
2010 HST Calibration Workshop
David Golimowski  (STScI)
The newly replaced CCD electronics box (CEB-R) for the Advanced Camera for Surveys (ACS) features a programmable SIDECAR ASIC manufactured by Teledyne. The CEB-R has fully restored the functionality of the ACS Wide Field Camera (WFC) and allows opt ...
2010 HST Calibration Workshop
Jay Anderson (STScI)
Based on a study of the trails seen behind warm pixels in long dark exposures, we have constructed an empirical model for the capture and release of charge that happens during readout of the WFC detector. The model assumes an even distribution of t ...
2010 HST Calibration Workshop
Paul Feldman (JHU)
Following the failure of STIS in August 2004, attempts to obtain ultraviolet spectroscopy and photometry of solar system objects shifted to the Solar Blind Channel (SBC) of the ACS. These included spatially resolved spectroscopy using the PR130L p ...

2010 HST Calibration Workshop
William van Altena (Yale University)
For the past 20 years, the HST has occupied a unique niche in astrometry, that of high-resolution imaging and interferometry-based astrometry. As a consequence of its small field of view, HST astrometry has been primarily oriented towards the observ ...
2010 HST Calibration Workshop
Vera Kozhurina-Platais (STScI)
We summarize the results of one year of Charge Transfer Efficiency (CTE) monitoring of the WFC3 UVIS in-flight detector, based on data acquired during the monthly internal Extended Pixel Edge Response (EPER) test. We present an algorithm for CTE a ...
2010 HST Calibration Workshop
Ed Nelan  (STScI)
HST's three Fine Guidance Sensors are critical for the fine pointing and stabilization of the observatory. The ability of the FGS to measure the position of a guide star to ~1 milli-arcsecond at 40 Hz also empowers it to serve as an astrometric and ...
2010 HST Calibration Workshop
Tony Sohn (STScI)
Over the past few years, it has been demonstrated that HST is well suited for high accuracy astrometric sciences. For example, HST's imagers have been used to measure relative proper motions of stars for deriving the internal dynamics of globular ...

Nathan Cole (JHU)
The Hubble Legacy Archive (HLA) is composed of hundreds of thousands of images taken by a number of different instruments all across the sky. A large number of these images are of overlapping fields and therefore contain many of the same objects. T ...

On the J.J. Drake "Ladder of Cosmic Sexiness," the calibration rung falls even below the lowly ones of "Stars" and "The Sun." Nevertheless, we cognoscenti of such things know full well that without good calibrations, there will be little signal and m ...
