info:eu-repo/semantics/other http://purl.org/dc/dcmitype/Dataset https://doi.org/10.17045/STHLMUNI.9907991 Sunburst Arc Magellan/MagE observations Thøger Emil Rivera-Thorsen Bayliss, Matthew Jane R. Rigby Astronomy, Astrophysics, and Cosmology Astronomi, astrofysik och kosmologi These are raw data files from the Magellan telescopes, MagE spectrograph, that are used in Rivera-Thorsen et al. 2019 (Science). All individual science integrations are included, as well as all the calibration frames: blueflat, redflat, bias, ThAr lamps, order definition flats, and flux calibration stars. Directories include data from three observing runs; the directory name gives the month and year the observations were obtained. All observations are of the galaxy known as the "Sunburst Arc", discussed in Rivera-Thorsen et al. 2019. The slit positions are as follows:- Img 1 / slit H-9 from August 2018 - Img 5 / slit "1" from May 2017 - Img 8 / slit H-2 from April 2018 - Img 10 / slit H-6 from April 2018 - No LyC slit H-3 from April 2018 Viewing the data: Data is stored in the Flexible Image Transport System (FITS) file format[¹], which is designed to store table or binary image data together with an ASCII header containing meta-data stored as a keyword-value pairs, of which some are mandatory and some are optional. Multiple software applications exist which can view and analyze FITS files. We recommend either DS9[²], QFitsView[³] or Ginga[⁴] packages, all of which are open source and freely available for both Windows, Mac OS X and GNU/Linux. Unpacking: The data is compressed in the .tar.gz format, which is natively supported on Mac OS X and GNU/Linux. On Windows, it can be opened with e.g. the 7-Zip software[⁵]. ------------- [¹]: https://en.wikipedia.org/wiki/FITS[²]: http://ds9.si.edu/site/Home.html[³]: http://www.mpe.mpg.de/~ott/dpuser/qfitsview.html[⁴]: https://ejeschke.github.io/ginga/ [⁵]: https://www.7-zip.org/ https://creativecommons.org/licenses/by/4.0/ Stockholm University Stockholms universitet 2019-09-26T00:00:00Z
