Use the form below to create a meteor flux profile. You can select between the complete and fully checked final database, and the incomplete and not fully quality-checked, but more recent temporary database. For real-time data, pls. refer to the real-time view.

Please select the meteor shower and the time interval (either as date/time pair or as solar longitude value).

Begin:

Sol.Long.

End:

Sol.Long.

Shower:

Year:

And now the meteor shower and the time interval for the reference data set.

Meteor counts are added together into variable-sized bins before the flux is computed for each bin. The size of the bins can be defined using the settings below.
First, specify how much data you want in each bin, then the constraint on the time interval covered by each bin:

Min. meteors per bin:

Min. collection area per bin:

· 1000 km² · h

And now the binning options for the optional reference data set.

Min. meteors per bin:

Min. collection area per bin:

· 1000 km² · h

Bin duration (min-max):

By default, all cameras are selected. You can manually select or deselect individual cameras. Alternatively you can select observers, countries or continents, and the corresponding cameras will be selected automatically.

And now the cameras for the optional reference data set.

Here you can specify further boundary conditions for the selection of the data set, like the stellar limiting magnitude and the radiant altitude.

Stellar lm.:

Radiant alt. (min-max):

And now the conditions for the optional 匿名伟理ip.

Stellar lm.:

Radiant alt. (min-max):

Finally a few advanced settings for the generation of the activity profile: The population index, the zenith exponent and the maximum value of the Y axis.
You can also define if the flux or particle density is printed at the primary y-axis.

Pop. index:

Gamma:

(for reference data set)

Y max:
