The photometric performance and calibration of wfpc2
Jon A. Holtzman,Christopher J. Burrows,Stefano Casertano,J. Jeff Hester,John T. Trauger,Alan M. Watson,Guy Worthey +6 more
TL;DR: In this paper, the photometric performance and calibration of the Wide Field Planetary Camera 2 (WFPC2) on the Hubble Space Telesopce (HST) were discussed, with particular attention given to charge transfer efficiency (CTE) effects, contamination effects in the ultraviolet (UV), and flat field accuracy and normalization.

TL;DR: The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.
Journal ArticleDOI
The performance and calibration of wfpc2 on the hubble space telescope

TL;DR: The Wide Field Planetary Camera 2 (WFPC2) was installed in the Hubble Space Telescope (HST) in 1993 December and has been providing high-quality images as mentioned in this paper.
Journal ArticleDOI
Benchmark problems for continuum radiative transfer - High optical depths, anisotropic scattering, and polarisation
Christophe Pinte,Tim J. Harries,Michiel Min,Alan M. Watson,Cornelis P. Dullemond,Peter Woitke,Peter Woitke,Francois Menard,María Carolina Durán-Rojas +8 more
TL;DR: In this article, the accuracy of seven independently developed radiative transfer codes by comparing the temperature structures, spectral energy distributions, scattered light images, and linear polarisation maps that each model predicts for a variety of disc opacities and viewing angles is evaluated.
Journal ArticleDOI
The Luminosity Function and Initial Mass Function in the Galactic Bulge
Jon A. Holtzman,Alan M. Watson,William A. Baum,Carl J. Grillmair,Edward J. Groth,R. M. Light,Roger Lynds,Earl J. O'Neil +7 more
TL;DR: In this paper, the authors derived a power-law form with dN/dM ∝ M^(-2.2) for M ≳ 0.7 M_☉, with a significantly shallower slope at lower masses, with the value of the slope depending on the assumed binary fraction and the accuracy of completeness correction.
