Computer simulations of interferometric imaging with the VLT interferometer and the AMBER instrument
We present computer simulations of interferometric imaging with the VLT interferometer and the AMBER instrument. These simulations include both the astrophysical modelling of a stellar object by radiative transfer calculations and the simulation of light propagation from the object to the detector (through atmosphere, telescopes, and the AMBER instrument), simulation of photon noise and detecto...
متن کاملThe VLT Interferometer Data Flow System: From Observation Preparation to Data Processing
In this article we present the Data Flow System (DFS) for the Very Large Telescope Interferometer (VLTI). The Data Flow System is the VLT end-to-end software system for handling astronomical observations from the initial observation proposal phase through the acquisition, processing and control of the astronomical data. The Data Flow System was first installed for VLTI first fringes utilising t...
متن کاملTOWARDS CHARACTERIZATION OF EXOPLANETARY ATMOSPHERES WITH THE VLT INTERFEROMETER V. Joergens and A. Quirrenbach
The direct observation of extrasolar planets and their spectra is coming into reach with the new generation of ground-based near-IR interferometers, like the Very Large Telescope Interferometer (VLTI). The high contrast between star and planet requires an excellent calibration of atmospheric distortions. Proposed techniques are the observation of color-differential or closure phases. The differ...
متن کاملThe VIMOS - VLT Deep Survey
Aims. We use the VVDS-Deep first-epoch survey data to measure the dependence of galaxy clustering on galaxy stellar mass, at an effective redshift z ∼ 0.85. Methods. We measure the projected correlation function, w p (r p), for sub-samples in the 0.5 < z < 1.2 interval covering different mass ranges between ∼ 10 9.0 and ∼ 10 11 M ⊙. We explore and quantify in detail the observational selection ...
متن کاملThe VLT Data Flow Concept
The size and complexity of the VLT require an integrated approach to the handling of science data associated with the operation of the observatory. In this paper, we present the VLT Data Flow concept: a strategy to fulfill the scientific requirements outlined in the VLT Science Operation Plan—namely, ensure optimal efficiency and a high, constant, and predictable data quality. The VLT Data Flow...
