Data

(BASELENGTH)

Float
(NUM_BASELENGTH)

m

Base lengthes

(PHASERMS)

Float
(NUM_BASELENGTH)

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

Flags

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_BASELENGTH
Number of baselength bins to determine the rms fluctuations
BASELENGTH
Actual baselengthes on which the rms phase is determined.
PHASERMS
rms phase fluctuations for these baselengthes.
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 PWVM  table(s). However the intent with this table is to get the information without reading data for efficiency!
