SAC download - processing time?
2013-09-24 10:05:07 - 2013-09-24 16:42:33
Greetings,  I am just wondering as to why the users are not allowed to download SAC soon after they fill in the necessary details. Is SAC not a freely distributed software? Why is there a "processing" time? In my view downloading SAC should be a less bureaucratic process than it is at present. Thank you.

KINST header
2013-09-23 17:44:08 - 2013-09-23 20:28:20
Hi, I was working with the sac header for a bunch of files, when i want writing the KINST variable, i see that it is only 8 characters long, so my instrument description is cut, i want write digitizer+sensor numbers (0681_T3305), so, is possible change the KINST from 8 to 16 characters? or, generate other variable (KSENS) to put the sensor number? or what other header variable is fine to use?

Running absolute mean normalization
2013-09-19 17:00:46
Hi All, I want to compute surface wave dispersion curves from cross correlation of ambient noises between seismic stations. For this purpose, I need to perform time domain normalization via "running-absolute mean-normalization". This method computes the running average of absolute value of the waveform in a normalization time window of fixed length and weights the waveform at the center of the window by the inverse of this average. This should have the effect of removing the large events and n… [more]
