In orbit performance of UVIT over the 5 years
S. K. Ghosh, P. Joseph, A. Kumar +21
Over the last 5 years, UVIT has completed observations of more than 500 proposals with ~ 800 unique pointings. In addition, regular planned monitoring observations have been made a…
Additional Calibration of the Ultra-Violet Imaging Telescope on board AstroSat
S. N. Tandon, J. Postma, P. Joseph +20
Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. (2017). The results reported earlier were based on the ground…
Development of image motion compensation system for 1.3 m telescope at Vainu Bappu Observatory
Sreekanth Reddy, Ravinder Kumar Banyal, Sridharan R +2
We developed a tip-tilt system to compensate the turbulence induced image motion for 1.3 m telescope at Vainu Bappu Observatory, Kavalur. The instrument is designed to operate at v…
Prospect for UV observations from the Moon. III. Assembly and ground calibration of Lunar Ultraviolet Cosmic Imager (LUCI)
Joice Mathew, B. G. Nair, Margarita Safonova +14
The Lunar Ultraviolet Cosmic Imager (LUCI) is a near-ultraviolet (NUV) telescope with all-spherical mirrors, designed and built to fly as a scientific payload on a lunar mission wi…
In-orbit Calibrations of the Ultra-Violet Imaging Telescope
S. N. Tandon, Annapurni Subramaniam, V. Girish +22
The Ultra-Violet Imaging Telescope (UVIT) is one of the payloads in ASTROSAT, the first Indian Space Observatory. The UVIT instrument has two 375mm telescopes: one for the far-ultr…
In-orbit Performance of UVIT and First Results
S. N. Tandon, J. B. Hutchings, S. K. Ghosh +23
The performance of the ultraviolet telescope (UVIT) on-board ASTROSAT is reported. The performance in orbit is also compared with estimates made from the calibrations done on the g…
In-orbit Performance of UVIT on ASTROSAT
Annapurni Subramaniam, Shyam N. Tandon, John Hutchings +23
We present the in-orbit performance and the first results from the ultra-violet Imaging telescope (UVIT) on ASTROSAT. UVIT consists of two identical 38cm coaligned telescopes, one…
Tests & Calibration on Ultra Violet Imaging Telescope (UVIT)
Amit Kumar, S. K. Ghosh, P. U. Kamath +11
Ultra Violet Imaging Telescope on ASTROSAT Satellite mission is a suite of Far Ultra Violet (FUV; 130 to 180 nm), Near Ultra Violet (NUV; 200 to 300 nm) and Visible band (VIS; 320…
