Astronomy with Vainu Bappu Telescope

Kameswara Rao, N (Astronomical Society of India, 1995-09)
Estimation and correction of the instrumental perturbations of Vainu Bappu Telescope Echelle spectrograph using a model-based approach

Chamarthi, Sireesha; Banyal, R. K; Sriram, S (SPIE-The International Society for Optical Engineering, 2019-11)

The Echelle spectrograph operating at Vainu Bappu Telescope (VBT), India, is a general purpose instrument used for many high-resolution spectroscopic observations. A concerted effort is being made to expand the scientific ...
Estimation of asymmetries in point spread function for the echelle spectrograph operating at Vainu Bappu Telescope for high precision radial velocity studies

Sireesha, C; Banyal, R. K; Sriram, S (SPIE--The International Society for Optical Engineering, 2018-07)

Precision in the Radial Velocity (RV) measurements depends upon the efficiency of the technique to remove instrumental artifacts from stellar measurements. Iodine absorption cell technique is being implemented for high ...
