filter.sol: Selection of visual meteor data by solar longitude
In MetFns: Analysis of Visual Meteor Data

Description Usage Arguments Details Value Note Author(s) See Also Examples

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

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

`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.

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.

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.

Argument data has to consist of the column named "Sollong".
