The user can select between b/w stars or color stars (with their O-E color index color coded). Plot a finding chart using a local copy of the USNO-B2.0 catalog. Given three coordinates on a sphere, calculate the area of a spherical triangle defined by these three points. Project coordinates from longitude and latitude to X/Y using a specified projection. Prepare DSS finding charts, with labels, compass, and slits. Project coordinates (longitude and latitude) to X-Y projection (no transformation).
Project coordinates (longitude and latitude) using the Stereographic polar projection. This is a map projection in which great circles and Loxodromes are logarithmic spirals. Project coordinates (longitude and latitude) using the Stereographic projection. Project coordinates (longitude and latitude) using the Sinusoidal projection. Project coordinates (longitude and latitude) using the polar projection (from north pole). Project longitude and latitude using a 'planisphere projection'. Project coordinates (longitude and latitude) using the Parabolic projection. Project coordinates (longitude and latitude) using the equal area Mollweide projection. Project coordinates (longitude and latitude) using the Mercator projection. Project coordinates (longitude and latitude) using the inverse of the equal area Hammer-Aitoff projection used in the FITS/WCS standard. Project coordinates (X and Y) using the inverse Gnomonic non conformal projection, Project coordinates (longitude and latitude) using equal area Hammer-Aitoff projection used in the FITS/WCS standard. The coordinates are projected on an ellipse with axis ratio of 2:1. Project coordinates (longitude and latitude) using the Hammer projection. Project coordinates (longitude and latitude) using the Gnomonic non conformal projection This is a nonconformal projection from a sphere center in which orthodromes are stright lines. Project coordinates (longitude and latitude) using a general cylindrical projection. Project coordinates (longitude and latitude) using the Conic projection.
Project coordinates (longitude and latitude) using the Cassini projection. Project coordinates (longitude and latitude) using the Bonne projection. Project longitude and latitude using Azimuthal equidistant projection (constant radial scale). The coordinates are projected on ellipse with axis ratio of 2:1. Project coordinates (longitude and latitude) using the Albers Equal-Area projection. Project coordinates (longitude and latitude) using equal area Aitoff projection. Given a star catalog plot star map with optional magnitude/color/type/proper motion ('/cy). Optionaly mark planets position, constellations and the milky way. Plot a monthly sky map with a naked eye stars for a given time and observer Geodetic position. Plot a list of coordinates (as dots/lines) on a map with a chosen projection. Number of functions added/updated in the last two months: 20 To figure out what new, sort the table by the "Last version" column. If you encounter any bugs please report to: eran dot ofek at weizmann dot ac dot il. Note that the "Reliability" column indicates the amount of debuggingĪnd tests a program was went through (1 is better). The table is sortable by any of the columns, by clicking on the column. The following table contains a list of all the available functions.Ī list of all the available catalogs and data files can be found
