Debian Astro Radio Astronomy packages

AOFlagger er et værktøj, som kan finde og fjerne interferens for radiofrekvenser (RFI) i radioastronomiske observationer. Koden er blevet optimeret for hastighed og præcision. Bruges som standard for LOFAR-radioteleskopet og er derfor i produktion. Programmet kan afvikles på en fuld automatiseret måde, men en grafisk grænseflade tilbydes til at analysere resultater og finjustere strategien. Det foretrukne filformat er formatet Casa Measurement Set (MS).

Denne pakke indeholder teksthovedfilen til at kompilere egne programmer mod biblioteket.

PURIFY er en samling af rutiner skrevet i C, der implementerer forskellige værktøjer for radiointerferometrisk billeddannelse inklusive filhåndtering (for både visibilities- og fits-filer), implementering af måleoperatøren og opsætning af forskellige optimeringsproblemer brugt for billeddekonvolution. Koden kalder den generiske pakke Sparse OPTimization (SOPT) for at løse billedoptimeringsproblemer.

Denne pakke indeholder udviklingsfilerne.

Pakken casacore indeholder de grundlæggende biblioteker for den gamle AIPS++/CASA-pakke. Denne opdeling blev lavet for at få en bedre adskillelse af de grundlæggende biblioteker og programmer. CASA er nu bygget oven på casacore.

Dette er Pythonomslaget omkring biblioteket.

WSClean (w-stacking clean) er en hurtig generisk widefield imager. Programmet bruger algoritmen w-stacking og kan bruge algoritmen w- snapshot. Fra og med februar 2014 er den 2-12 gange hurtigere end CASA's w- projektion, afhængig af tabelkonfigurationen. Programmet understøtter full- sky imaging og korrekt beam-korrektion for homogene dipole tabeller såsom MWA'en.

WSClean tillader Hogbom og Cotton-Schwab-oprydning, og kan rydde op i polarisationer sammen. Alle operationer udføres på cpu'en (programmet er ikke specialiseret for GPU'er).

Aperture synthesis or synthesis imaging is a type of interferometry that mixes signals from a collection of telescopes to produce images having the same angular resolution as an instrument the size of the entire collection. At each separation and orientation, the lobe-pattern of the interferometer produces an output which is one component of the Fourier transform of the spatial distribution of the brightness of the observed object. The image (or "map") of the source is produced from these measurements. Astronomical interferometers are commonly used for high-resolution optical, infrared, submillimetre and radio astronomy observations.

This package contains the header files for development.

SAGECal is a very fast, memory efficient and GPU accelerated radio interferometric calibration program. It can handle all source models including points, Gaussians and Shapelets. It can calibrate along hundreds of directions without running out of memory in almost real time. Intel Xeon Phi acceleration is also available. Distributed calibration using MPI and consensus optimization is enabled. Also tools to build/restore sky models are included.
