They allow model freedom between sites with data. Normally, the model will simply be smoothed into such a site from adjacent sites. However, sometimes model changes beneath a pseudo-site can improve data fit at other sites. With no pseudo-site, the routine which interpolates structure between data sites would not allow such structure to exist. Outputs surface magnetic and electric fields as well as MT data.
Outputs file containing the fields inside the model.
These can be used to restart the inversion for further iterations. They will greatly speed up the first iteration of the restart and in most cases, will permit using 32 bit rather than 64 bit arithmetic for the inversion. This will halve memory usage and substantially improve speed on many machines. Features that are in testing. Some may make it into the next release.
