progenner.progenInit(objs, SN1, SN2, IDs, progenType, printer=1, parentsOnly=1)[source]¶

Function used to initialize progen data.

Parameters:

objs : list

List of SPHGR objects

SN1 : int

Starting snapnum

SN2 : int

Ending snapnum (typically 0)

IDs : list

List of galaxy or halo indexes of interest

progenType : string

specify ‘galaxy’ or ‘halo’

This function does not return anything. However, it does add the following information to the root of your object (data not saved to disk):
