Hi,

Regarding hop + yt...

1. Does anyone know where to change the default overdensity of 160.0 ?  

2. Is it (160.0) the Delta-peak, as defined in the 1998 HOP paper ?

3. I have done 512^3 grid, 512^3 dark-matter (dm) particle Enzo Cosmology Simulations in a 200 Mpc/h Box using wmap5
   parameters... http://lambda.gsfc.nasa.gov/product/map/dr3/params/lcdm_sz_lens_wmap5.cfm
  
   I want to merge particles to represent atleast galaxies (Bigger groups are welcome too).
   What should I choose in place of 160.0 ? Will Delta-peak and Delta-outer adjust accordingly ?
