COSMICCALCULATOR(1) User Commands COSMICCALCULATOR(1) NAME CosmicCalculator - estimate cosmological values SYNOPSIS astcosmiccal [OPTION...] DESCRIPTION CosmicCalculator is part of GNU Astronomy Utilities 0.23. CosmicCalcu- lator will do cosmological calculations. If no redshfit is specified, it will only print the main input parameters. If only a redshift is given, it will print a table of all calculations. If any of the single row calculations are requested, only their values will be printed with a single space between each. For more information, please run any of the following commands. In par- ticular the second contains a very comprehensive explanation of Cosmic- Calculator's invocation: expected input(s), output(s), and a full de- scription of all the options. All options and their values: $ astcosmiccal -P Inputs/Outputs and options: $ info astcosmiccal Full section in manual/book: $ info CosmicCalculator Full Gnuastro manual/book: $ info gnuastro If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run: $ info help-gnuastro CosmicCalculator options: Input: -H, --H0=FLT Current expansion rate (Hubble constant). -l, --olambda=FLT Current cosmological cst. dens. per crit. dens. -m, --omatter=FLT Current matter density per critical density. -O, --obsline=STR,FLT Redshift from line and observed wavelength. -r, --oradiation=FLT Current radiation density per critical density. -y, --velocity=FLT Velocity of interest in km/s. -z, --redshift=FLT Redshift of interest. Basic cosmology calculations -a, --absmagconv Conversion to absolute magnitude (no unit). -A, --angulardiamdist Angular diameter distance (Mpc). -b, --lookbacktime Look back time to z (Ga: Giga Annum). -c, --criticaldensity Critical density at z (g/cm^3). -C, --criticaldensitynow Critical density now (g/cm^3). -d, --properdistance Proper distance to z (Mpc). -e, --usedredshift Used redshift in this run. -g, --age Age of universe at z (Ga: Giga Annum). -G, --agenow Age of universe now (Ga: Giga Annum). -L, --luminositydist Luminosity distance to z (Mpc). -s, --arcsectandist Tangential dist. for 1arcsec at z (physical kpc). -u, --distancemodulus Distance modulus at z (no units). -v, --volume Comoving volume (4pi str) to z (Mpc^3). -Y, --usedvelocity Used velocity (in km/s) for this run. Spectral lines -i, --lineatz=STR/FLT Wavelength of line (name or wavelength) at z. --lineunit=STR Unit ('angstrom', 'nm', 'microm' or 'm'). --listlines List pre-defined lines at rest frame. --listlinesatz List pre-defined lines at the given redshift. Operating modes: -?, --help give this help list --checkconfig List all config files and variables read. --cite BibTeX citation for this program. --config=STR Read configuration file STR immediately. --config-prefix=STR Custom prefix of option names config files. --lastconfig Do not parse any more configuration files. --minmapsize=INT Min. bytes to avoid RAM automatically. --onlyversion=STR Only run if the program version is STR. -P, --printparams Print parameter values to be used and abort. --quietmmap Don't print mmap'd file's name and size. -S, --setdirconf Set default values for this directory and abort. --usage give a short usage message -U, --setusrconf Set default values for this user and abort. -V, --version print program version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
