“…This format was designed specifically for astronomy (Ochsenbein et al, 2013). To its benefit, it is built on a standard markup language (XML; Bray et al, 2008) and thus is able to leverage existing software libraries to read and validate XML files.…”

a b s t r a c tWe present the case for developing a successor format for the immensely successful FITS format. We first review existing alternative formats and discuss why we do not believe they provide an adequate solution. The proposed format is called the Advanced Scientific Data Format (ASDF) and is based on an existing text format, YAML, that we believe removes most of the current problems with the FITS format. An overview of the capabilities of the new format is given along with specific examples. This format has the advantage that it does not limit the size of attribute names (akin to FITS keyword names) nor place restrictions on the size or type of values attributes have. Hierarchical relationships are explicit in the syntax and require no special conventions. Finally, it is capable of storing binary data within the file in its binary form. At its basic level, the format proposed has much greater applicability than for just astronomical data.

“…The object list is returned by the query service as a VOTable (Ochsenbein et al 2011), saved to disk and then locally searched for objects within the field of view of each candidate sky position. This currently takes the form of a radial proximity check, and in future versions will also include a simple analysis of a 20 arcsec SuperCOSMOS thumbnail image of the region.…”

Cone of Darkness: Finding Blank-sky Positions for Multi-object Wide-field Observations

We present the Cone of Darkness, an application to automatically configure blank-sky positions for a series of stacked, wide-field observations, such as those carried out by the SAMI instrument on the Anglo-Australian Telescope (AAT). The Sydney-AAO Multi-object Integral field spectrograph (SAMI) uses a plug-plate to mount its 13 × 61 core imaging fibre bundles (hexabundles) in the optical plane at the telescope's prime focus. To make the most efficient use of each plug-plate, several observing fields are typically stacked to produce a single plate. When choosing blank-sky positions for the observations it is most effective to select these such that one set of 26 holes gives valid sky positions for all fields on the plate. However, when carried out manually this selection process is tedious and includes a significant risk of error. The Cone of Darkness software aims to provide uniform blank-sky position coverage over the field of observation, within the limits set by the distribution of target positions and the chosen input catalogues. This will then facilitate the production of the best representative median sky spectrum for use in sky subtraction. The application, written in C++, is configurable, making it usable for a range of instruments. Given the plate characteristics and the positions of target holes, the software segments the unallocated space on the plate and determines the position which best fits the uniform distribution requirement. This position is checked, for each field, against the selected catalogue using a TAP ADQL search. The process is then repeated until the desired number of sky positions is attained.

“…The DSA module can then configured for read-only access to that database table before deployment through the Tomcat application server. Users submit Astronomical Data Query Language (ADQL) queries (Ohishi & Szalay 2005) to the DSA module, and query responses may be formatted as HTML, plain text or XML files formatted as VOTables (Ochsenbein et al 2004). In the case of remote files such as FITS files, images, or text files, the table can include URLs pointing to each dataset.…”

The eSDO project is a UK e-Science project funded by PPARC to develop solar algorithms, visualization tools and designs for a UK data centre that can be accessed through the UK virtual observatory in preparation for the Solar Dynamic Observatory (SDO) mission in 2008. Algorithms available for use by the solar community include helioseismology applications, coronal feature recognition, and wave power analysis. Visualization tools will allow users to vary time ranges, cadence and resolution and they view streams of images data from the Atmospheric Imaging Assembly (AIA) and Helioseismic Magnetic Imager (HMI) instruments. Finally, a prototype UK data centre will demonstrate efficient UK user access to SDO data through both AstroGrid searches and integration with the global SDO data archive.
