Calibration Problems on Schmidt Plates

  • R. Ziener
Conference paper

Abstract

The best way to calibrate Schmidt plates is by using similar objects to those under investigation as calibrators (for example: “small” galaxies with well-known magnitudes for “small” galaxies). This is a known postulate, often quoted by various authors, but it is difficult to put this rule into practice. Therefore astronomers often use artificial calibration; in most cases spot or wedge sensitometers.
