Radio observation in hydrogen line (1420MHz)
April 7, 2025 Admin

ezRA has identified an error in the recorded right ascension for data collected with one of the LRO hydrogen line radio telescopes. How does this error in right ascension affect the azimuth measurement that should be used for ezCol .txt data files?

More detail on the issue: The ezRA screen output during processing of data collected from LRO-H2 using ezCol had identified
