The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
DOTIFS: fore-optics and calibration unit design
Haeun Chung, A. N. Ramaprakash, Pravin Khodade +5
We present fore-optics and calibration unit design of Devasthal Optical Telescope Integral Field Spectrograph (DOTIFS). DOTIFS fore-optics is designed to modify the focal ratio of…
DOTIFS: spectrograph optical and opto-mechanical design
Haeun Chung, A. N. Ramaprakash, Pravin Khodade +10
Devasthal Optical Telescope Integral Field Spectrograph (DOTIFS) is a new multi-Integral Field Unit (IFU) instrument, planned to be mounted on the 3.6m Devasthal optical telescope…
DOTIFS: a new multi-IFU optical spectrograph for the 3.6-m Devasthal optical telescope
Haeun Chung, A. N. Ramaprakash, Amitesh Omar +4
Devasthal Optical Telescope Integral Field Spectrograph (DOTIFS) is a new multi-object Integral Field Spectrograph (IFS) being designed and fabricated by the Inter-University Cente…
Noise Characterization of IUCAA Digital Sampling Array Controller (IDSAC)
Sabyasachi Chattopadhyay, A. N. Ramaprakash, Bhushan Joshi +11
IUCAA Digital Sampling Array Controller (IDSAC) is a flexible and generic yet powerful CCD controller which can handle a wide range of scientific detectors. Based on an easily scal…
Multiple rooks of chess - a generic integral field unit deployment technique
Sabyasachi Chattopadhyay, A. N. Ramaprakash, Pravin Khodade +4
A new field re-configuration technique, Multiple Rooks of Chess (MRC), for multiple deployable Integral Field Spectrographs has been developed. The method involves mechanical geome…
A new photolithography based technique to mass produce microlens+fibre based integralfield units (IFUs) for 2D spectroscopy
Sabyasachi Chattopadhyay, Vishal Joshi, A. N. Ramaprakash +3
We present a novel photolithography based technique to efficiently fabricate microlens-fibre based Integral Field Units (IFUs). These IFUs are being developed for Devasthal Optical…
