Notes. Summary of initial conditions performed with the upgraded version of MOCCA code (i.e. MOCCA-SURVEY). All of the initial conditions were carefully chosen to test how to extend the GCs lifetimes, but with the goal of being able to reproduce the parameters of MW GCs (e.g., rhl, core radii (rc) total masses, NSG/NTOT) and to help design the initial conditions for the next, more comprehensive MOCCA-SURVEY. Some of the parameters are different for the two stellar populations FG and SG (e.g., N), and some of them are the same in both cases (e.g., rg). The meaning of the initial parameters are following: (a)Initial number of objects, only 400k+150k, 600k+200k, 800k+300k, 1.6M+600k models were computed. (b)King model parameter. (c)Upper mass limit for a single star (M). (d)Binary fraction. (e) Galactocentric distance (kpc). ( f) Half-mass radius for the first population (pc). (g) Concentration parameter between two populations (e.g., value 0.1 means that SG has a half-mass radius (Rh) ten times smaller than FG Rh). We did not compute all possible combinations of these parameters, only a subset of them. (h)Tidally filling model.(i)Only for rg = 2, W0,FG = 2,3.(j) Only for W0,FG = 2, 3.(k) Only for N = 600k+300k.
