DoubleStationMaps.py




software for creation of the maps for the double station video observations of the meteors
language - Python, using Skyfield library
optimized for Anaconda environment
source code download

entry parameters setup directly inside the code in section "Entry parameters"

time_step                   time interval for center of the field-of-view plotting (1 hour default)
obs_year                    year of observation
obs_month                 month of observation
obs_day                     day of observation
obs_hour_beg            beginning observation hour [UT]
obs_hour_end            end observation hour [UT]
obs_hour_map           time of the map

azimuthFOV, altitudeFOV        field-of-view center (in degrees, south = 0o)

station                      coordinates of the station - Kunžak, Ondřejov prepared - unused station commented ( # at the beginning of the line), it is possible to add more stations in the same format
station_name           name of the station

map_width_degrees        width of the map in degrees
limiting_magnitude         limiting magnitude for the stars


Software uses Hipparcos catalogue (stars up to 10th  magnitude), which is downloaded into the working directory during the first run (file hip_main.dat, 53 MB). Other downloaded files are efemerides of the planets (de421.bsp, 17 MB) and constellation coordinates table (constellation.fab, 10 kB). It is possible to download all the files before the first run and save them to software directory.

The map is plotted in a new window. It is saved automatically in the png format. Name and format of the file can be changed using  fig.savefig('FOV-chart.png', bbox_inches='tight') command at the end of the program.

Example:
Kunžak, 2020-12-14, 17 - 6 UT, interval 1 hour, field-of-view center (170, 45), size of the map 75 x 50 degrees, limiting stellar magnitude +7.0, maps for 20, 23 and 3 UT.

Ondřejov, 2020-12-14, 17 - 6 UT, interval 15 minutes, field-of-view center (45, 45), size of the map 30 x 20 degrees, limiting stellar magnitude +8.0, map for 23:30 UT
