Atmospheric conditions data
data0: atmospheric pressure in mbar (hPa) ;
data1: atmospheric temperature in degrees Celsius;
data2: relative humidity in %;
data3: if data3>=1, then it is Meteorological Range km ;
if 1>data3>0, then it is the total atmospheric coefficient (ktot) ;
data3=0, then the other atmospheric parameters determine the total atmospheric coefficient (ktot)
Eclipse information with the following:
List if eclipse times (refer to docs for details)
List of attributes (refer to docs for details)
Geographic position of eclipse
Nodes and apsides data with the following:
List of 6 positional values for ascending node
List of 6 positional values for descending node
List of 6 positional values for perihelion
List of 6 positional values for aphelion
Observer data
Details for data[] (array of six doubles):
data0: age of observer in years (default = 36)
data1: Snellen ratio of observers eyes (default = 1 = normal)
The following parameters are only relevant if the flag SE_HELFLAG_OPTICAL_PARAMS is set:
data2: 0 = monocular, 1 = binocular (actually a boolean)
data3: telescope magnification: 0 = default to naked eye (binocular), 1 = naked eye
data4: optical aperture (telescope diameter) in mm
data5: optical transmission
Visibility info with the following in data:
0: limiting visual magnitude (if data0 > magnitude of object, then the object is visible);
1: altitude of object;
2: azimuth of object;
3: altitude of sun;
4: azimuth of sun;
5: altitude of moon;
6: azimuth of moon;
7: magnitude of object.
