Integrated data access, visualization and analysis for Galactic Plane surveys: the VIALACTEA case
TLDR
A new VIALACTEA 3D Visual Analytics interface has been developed that provides integrated access and analysis of continuum and spectroscopic images together with catalogue data directly interfacing with the VLKB.
Investigating interoperability of the LSST data management software stack with Astropy
TLDR
The overlap between the LSst science pipeline software and Astropy software is described and areas where the LSST software provides new functionality are investigated, including the possibilities of re-engineering the LS ST science pipelineSoftware to build upon Astropy, includingThe option of contributing affliated packages.
VIALACTEA knowledge base homogenizing access to Milky Way data
TLDR
This contribution illustrates the current status of the VIALACTEA Knowledge Base and describes the database that allows data discovery through VO inspired metadata maintenance; illustrates the discovery, cutout and access services built on top of the former two for the users to exploit the data content.
The Astropy Project: Building an Open-science Project and Status of the v2.0 Core Package
The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of
LSST data management software development practices and tools
TLDR
This paper discusses the agile software development methodology and the API and developer decision making process for the LSST data management system, and the software tools that are used for continuous integration and deployment.
Modern Python at the Large Synoptic Survey Telescope
The LSST software systems make extensive use of Python, with almost all of it initially being developed solely in Python 2. Since LSST will be commissioned when Python 2 is end-of-lifed it is

World Coordinate Systems as Objects
TLDR
A new library which provides a flexible high-level programming interface for handling world coordinate systems in astronomy and for producing graphical output, and supports the Digitised Sky Survey plate solutions and the draft FITS WCS proposals.
Developments in the Starlink AST Library - an Intelligent WCS Management System
Recent developments in the AST library for managing WCS information are described. These include support for spectral coordinate systems, and compliance with FITS WCS papers I, II and III. 1. The
New Features in AST - a WCS Management and Manipulation Library
Recent developments in the AST library are described, including a Python interface, support for the FITS-WCS "-TAB" system for storing tabular co-ordinate information, and extended support for
Representations of time coordinates in FITS - Time and relative dimension in space
TLDR
This fourth paper deals with encoding time, extending the well-established World Coordinate System (WCS) framework and maintaining compatibility with the FITS conventions to describe rigorously the time coordinate.
Representations of world coordinates in FITS
The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of the detailed
Reimplementing the Hierarchical Data System using HDF5
IVOA Recommendation: Space-Time Coordinate Metadata for the Virtual Observatory Version 1.33
This document provides a complete design description of the Space-Time Coordinate (STC) metadata for the Virtual Observatory. It explains the various components, highlights some implementation
Implementation of -TAB coordinates in WCSLIB
This work describes the implementation of table lookup coordinates (-TAB) in WCSLIB subject, in particular, to the constraints that WCSLIB remain independent of the FITS I/O library (e.g. CFITSIO)
