xm_focal


NAME

xm_focal - Hypocenter format for the Geotouch program

SYNOPSIS

xm_focal - Input File Format

DESCRIPTION

The default format for focal mechanisms in Geotouch is UW pickfile


FORMAT


#################################
FOCAL-MECHANISM file is also in UW format:

Can have Several focal Mechanism Files input. Use: -F file1 -F file2.....

It is organized as pairs of A and M cards.
for a description of A-cards, see: xm_hypo.

An example of an A & M-card pair is:

A 9204230225 29.57 33N5728 116W1868 12.23 3.3 82/000 63 7 0.18 0.2BA CN
M F 345 45 G 255 90 U 165 45 V 435 0 P 219 29 T 470 30

M: strk1 dip1 strk2 dip2 pol1 dip1 pol2 dip2 p-axis pdip taxis t-dip

These pairs of cards must stay together and there may
be many concatenated in one file.
The first pair of strk-dip represents, by convention,
the focal plane and the second the auxiliary plane.
These can be switched by running a utility called switchfoc,
or they can be switched in Geotouch. See accelerator keys.

#################################
EXTENDED FOCAL-MECHANISM file is also in UW format:
An extended Focal Mechansim record includes a LAT-LON
added to the end of the M card.
This designated the position of the "exploded" location of the focal mechanism.
which can be saved with the menu-item: Dump ext under the FOcal menu.
After saving this file, future calls to Geotouch with the -Fext filename
will read in the focal mechanisms and their location for plotting after
hitting the "e" button.
