  6. random_king.cc March 2007 Bogdan Popescu

  7. random_king.cc The function used in computation (y = random input) output : x,y coordinates y input : random numbers in (0,1) interval March 2007 Bogdan Popescu

  8. random_king.cc - mass segregation Blue : segregation parameter 1 = 1.0 , no segregation Red : segregation parameter 1 = 0.5 Radial Position Relative to “Birth” Black : segregation parameter 1 = 0.2 Segregation parameter 2 controls the percentage of the stars not affected by the mass segregation. March 2007 Bogdan Popescu

  9. star_sky.cc input output *.trek files cluster.ini king.ini king.out *.list files run* scripts (to be used with SkyMaker) Features : - interpolation in the database (due to the lack of models, the Geneva Database contains many “-99” entries; Lagrange interpolation works for c isochrones) - rebinning (the stars are redistributed within the initial bin) *.list files are input for the SkyMaker program (E.Bertin, 2001-2007) One may use the run* scripts (runb, runv...) to generate *.fits images. SkyMaker is freely available at : ftp://ftp.iap.fr/pub/from_users/bertin/skymaker/sky_2.3.4.tar.gz (The recommended version is 2.3.4, especially for linux kernel 2.4.xx) One may want to edit *.sky configuration files according to a different telescope. The *.sky files included in the package correspond to the CTIO 1.3 m Telescope + ANDICAM in visible and IR. The path to SkyMaker should be in the skymaker.path. March 2007 Bogdan Popescu
