Debiasing astro-Photometric Observations with Corrections Using Statistics (DePhOCUS)
Tobias Hoffmann, Marco Micheli, Juan Luis Cano +5
Photometric measurements allow the determination of an asteroid's absolute magnitude, which often represents the sole means to infer its size. Photometric observations can be obtai…
