PET southern hemisphere latitude correction factor about newhall HOT 1 OPEN

Hello!

I can definitely see the omission versus the original source. Just applied the recommended changes, repeated the build, and all of the prior unit tests passed. This change is subtle enough that the uncorrected version really doesn't cause much distortion except in the specific situations identified.

Give the following JAR a spin, it's the current version of Newhall with the one amended line above, you should be able to run it with "java -jar Newhall-1.6.0-TESTBUILD-A.jar": https://s3-us-west-1.amazonaws.com/drww/Newhall-1.6.0-TESTBUILD-A.jar

If you find it works out better on some of the affected sets, I can fold this change into a new release, and increment the version counter accordingly. "1.6.1" has a good ring to it. If you can provide some datasets that demonstrate the problem (2-3 would be fine), I can also fold those into the unit test framework, to make sure this fix never regresses.
