Optimal coefficients for the group finders for 2MRS and SDSS.
|2MRS||0.64 Mpc||0.609 ± 0.004||0.707 ± 0.004||0.582 ± 0.008||0.321|
|SDSS||0.67 Mpc||0.522 ± 0.006||0.750 ± 0.026||0.822 ± 0.033||0.188|
Notes. The parameter blink,0 is the basic linking length, which corresponds to the distance to nearest visible neighbour at redshift zero. The coefficient αopt allows for proper scaling of the angular linking length, while the coefficient Ropt does the same for the radial linking length (in the redshift space). The coefficient λopt provides the optimized dependence on the scaling of the Malmquist bias correction. Stot is the median value of the group cost function calculated using all mock catalogues and the optimal coefficients.
