Celestia/1.7.0 Changes

List of changes in Celestia 1.7.0 (work in progress).

New parametersEdit

STC filesEdit

  • Temperature - in degrees Kelvin
  • BoloCorrection - Bolometric correction
  • Extinction - the number of magnitudes by which the star's light is extinguished

Spectral classesEdit

  • Y - for Y-class brown dwarfs
  • WO - for Wolf–Rayet stars of the oxygen sequence

SSC filesEdit

  • Mass - in Earth units
  • BondAlbedo - Bond albedo
  • GeomAlbedo - Geometric albedo; replaces Albedo
  • TempDiscrepancy - this is added to the calculated equilibrium temperature
  • Temperature - in degrees Kelvin; overrides TempDiscrepancy
  • TailColor - for comets

UnitsEdit

For many parameters, units can be specified in angle brackets, like this: Radius<rE> 1.1

LengthEdit

For e.g. Distance, Radius, SemiMajorAxis

  • <m> - meters
  • <km> - kilometers
  • <rE> - Earth radii
  • <rJ> - Jupiter radii
  • <rS> - solar radii
  • <AU> - astronomical units
  • <ly> - light-years
  • <pc> - parsecs
  • <kpc> - kiloparsecs
  • <Mpc> - megaparsecs

TimeEdit

For e.g. Period

  • <s> - seconds
  • <min> - minutes
  • <h> - hours
  • <d> - days
  • <y> - years

AngleEdit

For e.g. RA, Dec, ArgOfPericenter

  • <mas> - milliarcseconds
  • <arcsec> - arcseconds
  • <arcmin> - arcminutes
  • <deg> - degrees
  • <hRA> - hours of Right Ascension
  • <rad> - radians

MassEdit

For Mass

  • <kg> - kilograms
  • <mE> - Earth masses
  • <mJ> - Jupiter masses

Solar mass units weren't added, despite my[note 1] suggestion to do so.
