About sigma parameters #16

Closed ecastillot closed 2 years ago

Hi!

I don't understand very well the purpose of sigma parameters. Could you explain me them please?

max_sigma11
max_sigma22
max_sigma12

I am using GaMMA to associate seismic events in a regional network, I have noticed that by setting the max_sigma11=20 parameter, I have more associations than max_sigma11=2 (default parameter).

Hi, I have added the meaning of these parameters in the README file.
