Title:: Adding catalog data to object lists using the VO
Date:: 03 Apr 2025 09:45:51
Publisher:: The GAVO DC team
Description:: This brief tutorial shows you how to quickly add proper motions and photometry from Gaia to (almost) any object list using the Virtual Observatory. The VO protocol most suited to this kind of this is TAP ("table access protocol") and lets you transfer data and queries to database servers. In the example, we will be using TOPCAT as a client. There is no lock-in to it: There are libraries and other tools allowing an integration of TAP operations into arbitrary workflows – that's what standards are about. Tutorial supplements apply the techniques to Simbad, show how to use TAP from Python, and introduce UCDs.

Title:: Advanced Usage of HiPS and MOCs
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: This course introduces advanced usage of Hierarchical Progressive Surveys (HiPS) and Multi-Order Coverage (MOC) maps in Aladin. Using this document, you will learn how to handle a problem like : “I have a set of images. I would like to select regions in my observations that are above a given threshold in another survey (e.g. at low extinction), retrieve objects from very large catalogs (e.g. Gaia + WISE) in these non-trivial shapes and not-necessarily-connected regions, and combine them to visualise some quantities (e.g. color color diagram).“

Title:: An introduction to the CDS services and tools
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This tutorial shows how to use the CDS tools to gather information on specific astronomical objects. The tutorial covers the search for information on NGC 4039 in the CDS Portal, the search for data on NGC 4039 in Aladin, and the omparison of the coverages of Sky Surveys and select interacting galaxies that have SDSS and GALEX data.

Title:: A Short Course on ADQL
Short Name:: GAVO ADQL course
Date:: 03 Apr 2025 10:53:19
Publisher:: The GAVO DC team
Description:: This is a course on the Virtual Observatory's main query language ADQL (short for Astronomical Data Query Language), which is a SQL dialect standardised so users do not have to learn new languages each time they want to use a new resource. We also introduce the basic aspects of the Table Access Protocol TAP, which transports ADQL queries, their results as well as the metadata necessary to write meaningful queries. The course comes with many exercises, most of which also have solutions. We hope it is suitable for both self-study and as lecture notes in teacher-led situations.

Title:: A Short Course On PyVO
Short Name:: GAVO pyvo course
Date:: 03 Apr 2025 10:53:43
Publisher:: The GAVO DC team
Description:: This is a course on pyVO, an astropy-affiliated Python library implementing client parts for many protocols in the Virtual Observatory: Simple discovery protocols like SCS, SIAP, and SSAP as well as the sophisticated Table Access Protocol TAP, which allows users to send complex queries to remote tables and retrieve metadata-rich results. There is also an interface to the VO Registry to enable data and service discovery. The course comes with many exercises, most of which also have solutions. We hope it is suitable for both self-study and as lecture notes in teacher-led situations.

Title:: Astrometric Calibration using Aladin
Date:: 03 Apr 2025 09:45:51
Publisher:: The GAVO DC team
Description:: The VO client Aladin offers powerful facilities of creating an astrometrical calibration to images lacking WCS (World Coordinate System) information. This tutorial shows how to go about doing this for an image of the Ring Nebula in Lyr.

Title:: Classifying the SEDs of Herbig Ae/Be stars
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: The overall goal of this tutorial is to become familiar with VOSpec. For that, we are going to build the Spectral Energy Distribution (SED) of two Herbig Ae/Be stars, compare them and categorise them as group 1 or group 2 Herbig Ae/Be stars.

Title:: Compute Redshifts of Quasars Using SPLAT-VO
Date:: 03 Apr 2025 09:45:51
Publisher:: The GAVO DC team
Description:: This tutorial uses SPLAT-VO to search the VO registry for spectra of galaxies and quasars. From the obtained spectra, the Hydrogen Lyman Alpha line will be used to compute redshift and velocity

Title:: Data Discovery Using the Virtual Observatory Registry
Date:: 03 Apr 2025 09:45:51
Publisher:: The GAVO DC team
Description:: There are many ways to access registry data. A fairly powerful one is the Web Interface to the Relational Registry (WIRR for short) at http://dc.g-vo.org/WIRR To actually speak to the VO services discovered, clients speaking the service's protocols are still required. In this tutorial, Topcat plays that role. Starting from a simple use case, we work up to investigating the Tully-Fisher relation in different bands using independently discovered resources.

Title:: Determination of stellar physical parameters using SPECFLOW
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: An investigation of physical properties of the stars HD 232862 and Vega using the Specflow and Cassis tools.
