Data description
NUM_BASE_LENGTH	Int			Number of baselengths N_basept points sampling the function

Data
BASELENGTH	Float( N_basept)	m		Base lengths
PHASERMS	Float( N_basept)	deg		rms phase fluctuation
SEEING	Float			Seeing parameter, deduced for the LO1 freq.
EXPONENT	Float			Exponent of the power law of the phase structure function

Notes: This table holds informations on the phase structure and seeing.

TIME: Time midpoint
INTERVAL: Time interval over which the seeing information is extracted
NUM_BASE_LENGTH: Number of baselength bins N_basept determining the rms fluctuations
BASELENGTH: Actual baselengths on which the rms phase is determined.
PHASERMS: rms phase fluctuations for these baselengths.
SEEING: Seeing parameter, deduced for the LO1 frequency.
EXPONENT: Exponent of power law of the phase structure function

Comment: The phase structure function could be computed on-the-fly when accessing the data in the MAIN and or the TOTAL_POWER_MONITORING table(s). However the intent with this table is to get efficiently the information without reading data!
