SUMMARY

The discussion focuses on converting intensity values into magnitudes per square arcsecond, specifically converting an intensity of 130 counts per pixel using a radius of 5 arcseconds and a calibration constant of 30.8. The calibration constant represents the relationship between intensity and magnitude, allowing for accurate conversion. The formula for this conversion involves applying the given radius and calibration constant to derive the magnitude value. Understanding this process is crucial for accurate astronomical measurements.

PREREQUISITES
  • Astronomical photometry principles
  • Understanding of intensity and magnitude relationships
  • Knowledge of calibration constants in measurements

I need to convert the intensity, 130 counts per pixel into magnitudes per sq arc second. I have been given the radius as 5 arc sec, and a calibration constant, which is 30.8.

Only you know what the calibration constant and radius represent, so why not explain it to us?
