The PMO6 instrument

Please improve the description of the instrument! Two fully characterized instruments (absolute instruments): the "active" instruments measuring continuously and a "back-up" instrument ensuring redundancy and monitoring of the degradation of the active instrument.


Lifetime variation: 30 ppm/year

Absolute accuracy: 0.17%

Sampling rate: 1 solar total irradiance / 2 minutes

Duty cycle: 17%

Resolution: 50 ppm

Instrumental Noise

30 ppm (standard deviation of the "dark irradiance" every 2 minutes)

White noise, <0.4 ppm2/uHz

Temperature dependence: TBD

The following instrumental corrections will be needed:

Please refer to the VIRGO Operation manual for the observing sequence of the PMO6-V.
