A Discussion of the Magnitude Errors and Magnitude Scales of Meteor Observers in Sweden and Czechoslovakia
Abstract
Visual magnitudes of meteors obtained from observer estimates at Onsala Space Observatory, Sweden, and Skalnate Pleso Observatory, Czechoslovakia, are compared. The probable error in the magnitude estimates is computed from simultaneous observations of the same meteors by not less than two observers. A probable error of + or - 0.40 magnitude in a single estimate is calculated for the Swedish observers. The magnitude scales of the Swedish and Czechoslovakian observers are compared, and it is found that the mean magnitude difference between the two observer teams is 0.21 magnitude. Mean magnitudes estimated for Perseid meteors from extended observations are also compared by converting the Skalnate Pleso observations to the Onsala scale. It is concluded that there is no systematic discrepancy between the two magnitude scales.
