Star charts for GLOBE at Night 2014

All maps are for 21 h local mean time of the given date. Local time is different from the ‘civic’ time, if your longitude is different from that of the standard meridian for that time band. Being 10° westwards means your local time is 40 min lower. And during SummerTime, the local mean time is another 1 h less.

If you observe at another local sidereal times, you may use the 2012 maps or (having an alternative for more turbid air). 2011 maps or (even if the planets were elsewhere those years, and brighter or fainter). Those older maps are for January-April. A pleasant feature is, they have a screen-friendly variant of white stars on a grey background. Should I add that kind for 2014 too?

For cases the sky luminance is very high an almost no stars are visible (as during twilight) all-sky maps may be useful, available in subdirectories "A" or in "latitude" subdirectories.

Maps have been computed for a single transparency of the atmosphere, as expressed by the so-called extinction of starlight in zenith. It is an atmosphere with little haze, corresponding to zenith extinction of 0.25 mag.

Files like CygSep.pdf etc. within constell are symbolic links to the generic names like Sep19/Cyg/all.pdf. File all.zip contains all the date-named subdirectories.

Subdirectories within latitudes contain long-name symlinks to files in the date-named directories, a large *.pdf assembling all small maps and a smaller *A.pdf with all-sky maps combined. These subdirectories are the best URLs for an observer staying in a given latitude.

All maps have been produced by map_bsct programme, adapted to avoid plotting a large blob at [0,0] when using Hipparcos catalogue. Each set has been produced by its all.sh script, using a local template 20t.tex file (manually adapted) with descriptions. No manual editing of the output *.eps files had been made. Listing of the *.eps within subdirectories "single" is suppressed, but they are there, being smaller than pdfs made from them. All *.sh (bash) used are listed.
