Process based on:

Processing seismic ambient noise data to obtain reliable broad-band surface wave dispersion measurements (2007) G. D. Bensen et. al

and

Marco Calo, post-doc at UC Berkeley

Download data from IRIS:

a) For each station download a months worth of data.

- Change instrument réponseparamètres: zz,pp, constant for transfère function.

- Create a new folder with month you are working with.

- Comment this part out when after going through the code for the first time.

2) Cross correlate data.

- "Corr_stage_1moise_2013.m"

- What you need, (in the month folder):

+ Have "Corr_stage_1moise_2013.m"

+ Modify what Julian Days you are looking at in "ListJourJulien.asc"

- Make sure you write change the month name.

- Will save as ".freb_0.001_frehaut_0.1_z_b"

c) To see what you are doing;

- Be in folder with "FicCorrSign.freb_0.001" and "JAN" (folder with month, this is must optional)

3)Stacking;

- "StackCorr_stage_v4"

- You don\'t have to be in folder with cross correlations. Be one folder above.

- You need to have your list of stations

4)To visualize stack: "VissuCorrStack”

-Need "CorrStack_bM_031.mat" (Cross-stacked stuff).
