Data
Examples of the data are as follows:
EPOCH:
data.epoch.data[0] = 1363496400
This data is presented as number of seconds since January 1, 1970 in UT. The example above converts to 2013-03-17/05:00 UT. There are 1200 time values stored in each file.
LATITUDE:
data.latitude.data[0] = 45.0000
This data is the geographic latitude in degrees of the 400x400 grid of data points. There are 400 latitude values stored in each file.
LONGITUDE:
data.LONGITUDE.data[0] = 180.000
This data is the geographic longitude in degrees of the 400x400 grid of data points. There are 400 longitude values stored in each file.
CONDUCTANCE:
data.conductance.data[0] = -1.0000000e+31
This data is the Hall conductance in mho measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no conductance was measured here. A valid value would be something in the range of 0.00043800000 to 88 mho. There are 1200x400x400 conductance values stored in each file.
ENERGY FLUX:
data.eflux.data[0] = -1.00000e+31
This data is the energy flux in ergs/cm^2/s measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no energy flux was measured here. A valid value would be something in the range of 0.01 to 1100.0000 ergs/cm^2/s. There are 1200x400x400 energy flux values stored in each file.
ENERGY:
data.energy.data[0] = -1.00000e+31
This data is the energy in keV measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no energy was measured here. A valid value would be something in the range of 0.01 to 22 keV. There are 1200x400x400 energy values stored in each file.
