Description
For rake angles of 181-360, the displayed focal mechanism is incorrect (fortunately obviously so), whereas for the mathematically equivalent rake angle range of -180 to 0 the mechanism is displayed correctly. The following demonstrates this. Both mechanisms represent the identical normal faulting earthquake, but only the one to the left is displayed correctly
psmeca -R-53.5/-50.5/-33.25/-28.75 -JM13 -Sa0.4 <<EOF
-51.686 -31.002 24.5 40 62 -103 5.0 0 0
-51.186 -31.002 24.5 40 62 257 5.0 0 0
EOF
Expected behaviour:
1. Treat rake angles 180-360 as equivalent to rake angles -180 to 0 degrees
2. If values for angles are outside expected range, issue warning message

This was fixed a long time ago in GMT 5 but probably ignored in GMT 4. I just added the same fix there as well. I recommend you move to GMT 5.
