filter.imocode: Selection of visual meteor data by IMO observer code

Description

Selects data for a given visual meteor dataset and specified IMO observer code.

Usage

filter.imocode(data, imocode)

Arguments

data
data frame consisting of visual meteor data (rate or magnitude data).
imocode
character string consisting of five capital letters which represent IMO observer code.

Value

  • filter.imocode returns data frame with the same number of columns as the argument data, containing values corresponding to the observer with specified IMO code.

Details

IMO observer code is a combination of the first three letters of the last name and the first two letters of the first name. List of IMO observer codes can be found in the dataframe vmdbpers. IMO observer codes are unique, meaning that if 5-letter combination is already used, the observer gets modified IMO code.
