'g2Ptole' and 'g2Ph' = Ptole- and Phase-Metric computed using lalapps_getMetric

The other metrics were computed using FstatMetric (lalCommitID: d05e0efe2ec393615fc65bb7dbf39315dd35bda8, lalappsCommitID: c13d7740f83622a0105c3075ea86b1d775749d3d)

Comparison of new FstatMetric_v2 to old FstatMetric code:

Running script checkFstatMetric_v2.m version (f00ea062e51f0da972ac577317a0cdbc6df93137) using lal/lalapps versions: (lalCommitID: ec33e59950eca7d7846307088b94fac010329a10, lalappsCommitID: 82d8bd7f9d581cdb55a49853a52db894785151c4)
