Comment 2 for bug 1046720

Test data for hazard curve calculation with ground motion fields.

The files gmf_values_site1.dat and gmf_values_site2.dat contains ground motion field values for 2 sites both associated to a duration T = 1000 year.

For intensity measure levels [0.01, 0.1, 0.2] the probabilities of exceedance for site 1 and investigation time equal to 1 year are (rounding to 5 digits):
[0.63578, 0.39347, 0.07965]

and for site 2:
[0.63578, 0.28609, 0.02664]
