mag.distr: Summarized magnitude distribution

Description

Table and graphical representation of summarized magnitude distribution for a given magnitude dataset, specified meteor shower and time period.

Usage

mag.distr(data,date.start,date.end,shw)

Arguments

data

data frame consisting of visual meteor magnitude data.

date.start

character vector or factor specifying start date, given in "%Y-%m-%d %H:%M:%S" format (UTC timezone).

date.end

character vector or factor specifying end date, given in "%Y-%m-%d %H:%M:%S" format (UTC timezone).

shw

character string consisting of three capital letters which represent meteor shower code.

Value

Table and plot of summarized magnitude distribution consisting of histogram and boxplot.

The histogram cells are intervals of length 1, with midpoints at magnitudes -6 to +7.

Details

Summarized magnitude distribution is formed by summing magnitude frequencies of all observing time intervals.
