filter.mag: Selection of visual meteor data by limiting magnitude

In MetFns: Analysis of Visual Meteor Data

Description

Selects data for a given visual meteor dataset and specified limiting magnitude or interval of magnitudes.

Usage

filter.mag(data,mag.low=1,mag.up = 8)

Arguments

data	data frame consisting of visual meteor rate data.
mag.low	numeric vector with value between 1 (default) and 8, specifying lower boundary of limiting magnitude.
mag.up	numeric vector with value between 1 and 8 (default), specifying upper boundary of limiting magnitude.

Value

filter.mag returns data frame with the same number of columns as the argument data, containing observations with the limiting magnitudes between mag.low and mag.up.

Note

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

Examples

## select visual meteor rate data for 13th August 2015, limiting magnitude between 5.5 and 6.5
rate_13.08<-filter.date(rate2015,date.start="2015-08-13",date.end="2015-08-13")
filter.mag(rate_13.08,mag.low=5.5,mag.up=6.5)

## select visual meteor rate data for the 13th August 2015 and limiting magnitude above 6
filter.mag(rate_13.08,mag.low=6)
