SUMMARY

The discussion focuses on converting measured satellite magnitudes in four filters to Radiant Intensity (RI). It emphasizes the necessity of integrating the solar spectrum over the specific filter bandpasses to determine the visual magnitude of the sun in those filters. The relationship between the satellite's magnitude and the solar visual magnitude is crucial for accurate RI calculation. Participants highlight the importance of using precise equations to facilitate this conversion process.

PREREQUISITES
  • Understanding of satellite photometry and magnitude systems
  • Knowledge of solar spectrum integration techniques
  • Familiarity with filter bandpass characteristics
  • Basic proficiency in using radiometric equations for intensity calculations
NEXT STEPS
  • Research methods for integrating the solar spectrum over specific filter bandpasses
  • Study the equations relating visual magnitude to Radiant Intensity
  • Explore software tools for photometric calculations, such as AstroPy
  • Investigate the effects of different filter types on magnitude measurements
USEFUL FOR

Astronomers, astrophysics researchers, and satellite observation specialists seeking to convert satellite magnitudes to Radiant Intensity for analysis and application in observational studies.

TL;DR
Asking how I would convert measured magnitudes to radiant intensity.
I have the measured magnitudes of a satellite object in four filters and I want to convert this into into Radiant Intensity. I was told that if I integrated the solar spectrum over my filter bandpasses , I could obtain the visual mag of the sun in each of these filters and use this to obtain the RI of the satellite (knowing the satellite mag), However I am unsure of the correct relationships/equations needed to do this.

Any help would be appreciated.
