The phases Pis and Sis were more recent additions to the tables folder. I am
wondering if they are for real. They are not formatted correctly, and I find
that the arrival times are independent of event depth. I have never before
found a listed phase which has no dependence on depth. Their distance range
is short, only 1.11 degrees. Unless somebody can tell us more about these
phases, do not add them to your phase list.

P.S.  By the way, the JB files in the Tables folder are in text format, and
can be opened and inspected using NotePad. You can plot them by downloading
my TravelTime.exe program, at

The table files are mostly from 1995 but the PI91 file is dated 1998.
