Photometric Systems: Methods Of Reduction
Scientific paper
Most photometric research programmes in astronomy are conducted using standard filters of one kind or another. This enbable the results from these programmes to be directly compared with others which have used the same filters. If a programme is carried out using non-standard filters for which no stellar magnitudes exist, then comparisons may be made through an intermediate step using synthetic magnitudes and colours. These are computed from the energy distribution of stars of different spectral type convolved with the transmission, sensitivity, and reflectivity functions of the telescope optics and detector system, and the known properties of Earth's atmosphere and the interstellar medium. This paper describes how that may be achieved and gives as an example the filter system used in the MOA experiment.
