1. DESCRIPTION
################
Simulation results of an standard ETAS model as a branching process. Using a two seed version of the RANDU linear congruential pseudorandom number generator. The offspring number is a Poisson number given the rate n(M) (see below). Details of simulation procedure can be found in reference [1]: 'Topological properties of epidemic aftershock processes', by J. Baró submitted to J. of Geophysical Research - Solid Earth (JGR-B)

##############
2. INPUT PARAMETERS
##############
The input parameters (see reference for details) for each raw and processes data-file are indicated in the prefix of the file: "ETASbranch_b(b)r(r)N(nb)*"

- M0(= 1) = magnitude of completeness (arbitrary for the study of topological properties of trees)
- (b)  = b-value (arbitrary for the study of topological properties of trees)
- (nb) = average branching ratio
- (r)  = ratio a/b

The b-value defines the distribution of event-magnitudes: P(M) = 10^(b*(M-M0)) . The nb and a define the productivity law: n(M) = (nb*(b-a)/b)*10^(a*(M-M0))

3. TYPES OF FILES
#################

3.1. Raw data:
--------------

42 x "*.Seq" files with input b=0.50 and different nb, r values. Raw data from simulation code. (all cases, simulated with 10^5 background events)
Each row represents an individual event in the point process, or element of the simulated branching forest.
Columns description (9 columns x data point):
  c0:Time (arbitrary, used here as id.)
  c1:Magnitude of the event
  c2:Identification number of the cluster or tree
  c3:Depth of the event in the tree structure (background events have Depth = 0)
  c4:Time of the direct parent of the event (set to -1 for background event)
  c5:Magnitude of the direct parent of the event (set to -10 if background event)
  c6:Time of the event initiating the tree (set to own time if background)
  c7:Magnitude of the event initiating the tree  (set to own magnitude if background)
  c8:N or offspring number of the event. (Events are leafs if N=0)

3.2. List of trees
------------------

53 x "*TopoTrees.dat" files obtained from simulations (after processing of *.Seq files. Files ending with "N0.99", "N0.50" obtained from 10^5 background events from files above. Files ending with "N0.500*" obtained from 10^7 simulations)
Each row represents an individual tree constituted by one or several causally connected events of the simulated branching forest. Files used to generate fig. 4 of ref. [1]

Columns description (8 columns x data point):
  c0:Maximum Depth of the tree
  c1:Number of events in the tree
  c2:Average depth of leaves
  c3:total number of leaves
  c4:Sum of the depth of all leaves (=c2*c3)
  c5:(=0) not used
  c6:Magnitude of root
  c7:Maximum magnitude of an event inside the tree

4.3. Tree-size frequencies
--------------------------

18 x "*TopoTrees.FK" files obtained from "*TopoTrees.dat". Contains the frequencies of tree-sizes. Each raw number correspond to a size. Each value corresponds to number of incidences of that size divided by total number of events (10^5 in all cases). Notice that last point is missing at size = max-length, freq.= 1.0 / total number of events. Files used to generate fig. 3 of ref. [1]
