Meanings
-
A measurement that gives an indication of size but which is not a true magnitude. For example some pseudomagnitude values can be negative.
It makes use of two new reddening-free concepts: a distance indicator called pseudomagnitude, and a quasi-experimental observable that is independent of distance and specific to each star, called the differential surface brightness (DSB).
