Paranal Service Mode User Satisfaction Survey Results

Published: 24 Nov 2017

The User Support Department (USD) extends its thanks to all those Principal Investigators and their Phase 2 delegates who filled in this September's online Paranal Service Mode User Satisfaction Survey. A total of 194 responses were received from our targeted campaign. Where possible, we have contacted those respondents who provided detailed comments. A summary report based on this latest User Satisfaction Survey is now available.

ALMA Cycle 5

Published: 23 Nov 2017

ALMA Cycle 5 started successfully on 1 October 2017. Principal Investigator observations started with the longest configurations (~16 km). Progressively smaller baselines will be adopted over the course of next year, reaching the most compact configurations by July 2018. ALMA users may check the configuration schedule and the real-time observing status at any time.

Workshop: Submillimetre Single-Dish Data Reduction and Array Combination Techniques

Published: 22 Nov 2017

ESO Headquarters, Garching, Germany, 15–16 March 2018

Single dish submm facilities provide an essential complement to ALMA interferometry data, but require a set of special observing techniques and data reduction software that are different from radio and mm facilities. In this ESO-Radionet workshop, we will train both novice and more experienced users on how to optimally analyse data from telescopes such as APEX. The combination of interferometer with short baselines and single dish data is required for sources containing emission on spatial scales larger than the largest recoverable scales. However the ALMA observatory does not yet provide such merged data products, and is not planning to do so in the near future. In the workshop, we will introduce different combination techniques such as feathering and joint deconvolution.

Presentations from QUESO Workshop 2017

Published: 17 Nov 2017

The submillimetre/mm/cm QUESO Workshop 2017 (Centimetre-Sub-Millimetre Q&U (and V) European Southern Observatory Workshop) was held at ESO Garching from 25-27 October, 2017. The presentations are now available to download from the programme page.

VPHAS+ Public Survey Updated Band-Merged Catalogue

Published: 14 Nov 2017

Six months of observations have been added to the third catalogue release (DR3.2) from the ESO Public Survey VPHAS+ (VST Photometric H-alpha Survey of the Southern Galactic Plane and Bulge). The updated catalogue release version DR3.2 includes aperture-matched band measurements derived from all calibrated images of sufficient quality that were acquired until 30 September 2015 under ESO Programme 177.D-3023(B,C,D,E, F, G, H). The current catalogue release covers about 1200 square degrees, which correspond to over half of the VPHAS+ footprint targeting the Southern Galactic Plane.
