filter.sol: Selection of visual meteor data by solar longitude

Description

Selects data for a given visual meteor dataset and specified interval of solar longitudes.

Usage

filter.sol(data,sol.low,sol.up)

Arguments

data

data frame consisting of visual meteor data (rate or magnitude data).

sol.low

numeric vector specifying lower boundary of solar longitude in degrees.

sol.up

numeric vector specifying upper boundary of solar longitude in degrees.

Value

filter.sol returns data frame with the same number of columns as the argument data, containing observations with solar longitudes between sol.low and sol.up.

Details

The function filter.sol selects data with solar longitudes bounded by sol.low and sol.up. In selection of the data, solar longitude corresponding to the middle of the observing time period is used.
