Data description

NUM_BASE_LENGTH

Int Number of baselengths Nbasept points sampling the function

Data

BASELENGTH

Float( Nbasept) m Base lengths

PHASERMS

Float( Nbasept) 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 Nbasept 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!
