Subject: laser crzstal temp settings for both cavities 

currently the setting for the NPRO temp slider is:

  • refcav 1: 0.7341
  • refcav 2: 0.7570

changes for refcav2 are large due to the missing insulation and heater on that chamber. The LIGO refcav heaters don"t fit as the position of the connections to the main chamber tube are different (and in quantity too). changes over the last couple of hours are .7350 to .7570, which is abou 20MHz and so more than the tuning range of the VCO
