NAME std - standard star search SYNOPSIS std [search] [display] DESCRIPTION std is a command-line tool which allows to browse an inter- nal database of infra-red standard stars. std contains internally a database of more than 800 stars, built-up by J.G.Cuby. From the catalog, it is possible to select stars based on a position criterion, name, sky region, or magni- tude in a given band. Results can be displayed in different formats. SEARCH OPTIONS Search options are related to different user-defined cri- teria to select a number of stars in the database. The fol- lowing are implemented: -p/--pos HH MM SS HH MM SSorDD DD If this is the only search criterion on the command- line, only the closest star to this position will be returned. The position can be provided as hours, minutes, seconds for RA and DEC (6 values expected) or simply in degrees (2 values expected). -r/--radius value Together with the --pos option, this specifies a radius around a sky position. All stars within this region will be selected. -n/--name value To search stars by name. The provided value is a regu- lar expression, all stars matching it will be selected. -m/--mag band min max To search stars by magnitude range in a given wave band. Supported wave bands are: J, H, K, Ks, L, Lprime, M, Mprime. Minimum and maximum magnitudes define a range into which all stars are selected. DISPLAY OPTIONS -k/--key To display the output in keyword format. FILES The star database contains the following informations about stars (in this order): Name of the star RA and DEC in HH:MM:SS format Spectral type Magnitudes in J, H, K, Ks, L, M. EXAMPLES To print out the closest star from position '10 12' (in degrees): std --pos "10 12" To print out all stars within 10 degrees of this position: std --pos "10 12" --radius 10 To print out all stars which name matches "FS*" std --name "FS*" To look for all stars in band L having a magnitude between 5 and 6: std --mag "L 5 6" BUGS It is not yet possible to combine selection criteria.
