Radio astronomers debate why spectral units cause confusion
Original: This question confounds every radio and radar astronomer, because we always measure things in terms of energy per Hz (or
A radio and radar astronomer has weighed in on a puzzling question about measurement conventions, noting that his field habitually measures signals in energy per hertz of spectrum, using kHz, MHz and GHz units. He adds that infrared astronomers complicate matters further by insisting on inverse centimeters instead, a practice he admits he finds confusing.
Why now: Scientists are discussing differing unit conventions across astronomy subfields.

- This question confounds every radio and radar astronomer, because we always measure things in terms of energy per Hz (or per kHz or MHz or GHz) of spectrum. Although the infrared astronomers sometimes insist on doing things in inverse centimeters. That confuses me. QT Dan Falk… · michael_w_busch@mastodon.online
