Astr O
ABOUT – ASTROMATIC.NET About – Astromatic.net. Astr O matic.net is a website dedicated to astronomical pipeline software. Astr O matic software is meant to be run in batch mode on large quantities of data, mostly on Unix platforms, with minimum human intervention. It is currently in use in various image survey pipelines including TERAPIX, the Dark-EnergySurvey
EYE – ASTROMATIC.NET EyE – Astromatic.net. In EyE (Enhance Your Extraction) an artificial neural network connected to pixels of a moving window (retina) is trained to associate these input stimuli to the corresponding response in one or several output image (s). The resulting filter can be loaded in SExtractor to operate complex, wildly non-linear filters on VISIOMATIC – ASTROMATIC.NET VisiOmatic – Astromatic.net. Visi O matic is a web client for the IIPImage server, which allows to visualize and navigate through large science images from remote locations. It is based on the Leaflet Javascript library, and works on both touch-based and mouse-based devices. Authors: Emmanuel Bertin, ( IAP ), Chiara Marmo ( GEOPS ),Ruven
WEIGHTWATCHER
WeightWatcher – Astromatic.net. WeightWatcher is a program that combines weight-maps, flag-maps and polygon data in order to produce control maps which can directly be used in astronomical image-processing packages like Drizzle, Swarp or SExtractor. Authors: Chiara Marmo & Emmanuel Bertin. SEXTRACTOR – ASTROMATIC.NET Package updates. March 20, 2014 – 18:36. At last! By popular request, the official versions of nine AstrOmatic packages have been updated and include all the improvements from the development versions.

STIFF 2.1 RELEASE
STIFF V2.1 has been released! This small update to STIFF 2.0 is now compatible with Mac OS X (thanks to E.Pietriga) and has a new COPY_HEADER option to include WCS information in the TIFF file. This makes it possible to load STIFF colour images converted to JPEG right into the Aladin sky atlas with full astrometric information (thanks to R.Barbá for the idea).REDMINE

As already reported here and here, scientific code compiled with the Intel C compiler (icc) used to get a “free” 10-30% speed boost compared to code compiled with the Gnu compiler (gcc), thanks mostly to Intel’s vectorised math routines. gcc is now at version 4.4, and icc at version 11.1, and this remains true, in both 32 and 64 bits.

Using Celestia I generated an RGB colour image of Saturn seen from Earth at the end of July 1610. The angular equatorial diameter of Saturn was then 18.8". Pixels in the full image measure 0.145"×0.145". Galileo observed Saturn probably with a telescope like the one shown on the left, for which the effective aperture diameteris about 15mm
TUNING UP YOUR DISPLAY FOR OPTIMAL VIEWING OF ASTRONOMICAL Tuning up your display for optimal viewing of astronomical images. Displaying in a proper and consistent way deep-sky astronomical images on a computer screen is not as straightforward as it seems, even with recent monitors. Much of the fine image details lie in the dark part of the images, whose brightness can hardly be pushed up without FEATURE #1476: IMPLEMENT ITERATIVE ASTROMETRY SOLVER This is to allow very large solutions (>100,000 unknowns) and proper motions to be managed in SCAMP. As the problem cannot generally be considered sparse, we have somehow run out of options for compressing the normal equation matrix.

VISUALIZING LARGE SCIENCE IMAGES IN A WEB BROWSER Posted by Emmanuel insoftware ,

March 25, 2014 – 2:01Comments (0)
In this paper , we propose a scalable client-server system for web-based streamed viewing and zooming of large science images in Astronomy applications. User interfaces based on this framework are embeddable in regular Web pages, blog posts, or wiki entries. Targeted use cases include visual survey data query and exploration, remote image quality control, educational or training demos and interactive press release material. Visualizing and navigating through large astronomy images from a remote location with traditional astronomy display tools can be a frustrating experience in terms of speed and ergonomics, especially onmobile devices.
IIPImage is a versatile system for scientific image visualization and remote analysis, entirely based on Web technologies. IIPImage has a long history and finds its roots in the mid 1990’s in the cultural heritage field where it was originally created to enable the visualization of high resolution colorimetric images of paintings. In order to deal
with astronomy science images we brought new features to the IIPImage server , and set up an internal pipeline entirely in floating-point format. A variety of web clients already exists for IIPImage. For this project we focused on interfaces for both planetary data andcelestial images.
Visi_O_matic
is an open source celestial image viewer developed at Astr_O_matic __. The current prototype is based on the Leaflet Javascript library, and works on both touch-based and mouse-based devices. Please check out the Visi_O_matic homepage for information and demos.Search Astromatic
