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…

Annapurni Subramaniam, Snehalata Sahu, Joseph E. Postma +15
We present the UV photometry of the globular cluster NGC 1851 using images acquired with the Ultra-violet Imaging Telescope (UVIT) onboard the ASTROSAT satellite. PSF-fitting photo…
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…
