![]() The units for the columns in the MAST version have been converted to slightly different units than what is documented in Tonry et al. The Refcat2 data are also available as gzipped CSV files in Dec zones, with columns converted to standard astronomical units. Note this software is provided "as-is" by the author and is not maintained by MAST. The original catalog has the following name convention: hlsp_atlas-refcat2_atlas_ccd_-m-_multi_v1_cat.tbz Tonry to Refcat2 data files in a directory, and returns all the stars within a distance of a given coordinate. A program refcat.c with man page refcat.man is provided by J. 2018. These are compressed tarballs of 64800 CSV files for each coordinate square degree. Instructions for printing:įor best results print the atlas as explained in the following diagram, at 600dpi resolution (at least), preferably in color, on A4 paper, with "reduce to printer margins" option checked.The original catalog formats are organized into magnitude chunks, as described in Tony et al. Source charts were generated in "TheSky 5" program ( Software Bisque ® all rights reserved) and converted to PDF (vector graphics). To print the atlas Adobe Acrobat reader is required. It covers whole sky for observers living from 32°N and higher. The atlas is less suitable for southern hemisphere observers, since it plots the sky only down to declination of -58º (south). Labels of deep sky objects (common names and catalog numbers) are plotted down to 12th magnitude, while fainter DSO (down to 12.5-13.5th magnitude) are displayed without a label - this may give a hint whether a particular object is reachable. ![]() Stars down to 9.5th magnitude from Tycho, Hipparcos and Guide Star catalogs are plotted and labeled with common names, Bayer and Flamsteed designations.įor select double stars - separation in arc-seconds is listed. ![]() Shaded Milky Way, RA/DEC grid, ecliptic, constellation lines.Index charts, constellation index, and "next-page" direction marks.Common names of deep sky objects and stars.Marked double stars up to 8.5th magnitude.Triangulum region chart example Features: ![]()
