DARM open loop template updated

The dtt template for DARM open loop measurement has been updated to take the new elliptic filter (alog 20612) into account. This covers a frequency band of 7-1200 Hz. Additionally, a few frequency points are slightly shifted to avoid notchy places.

The dtt file is saved in SVN at

Also, the frequency vector for Pcal Y sweep is adjusted to the one for the new DARM template. I could not fully test it out because of a lockloss in the middle of the measurement. However, since I interpolated the amplitude from 2015-08-17_PCALY2DARMTF_logscale.xml, the signal-to-noise ratio should be as good as it in principle. The new Pcal Y template is saved in SVN at
