Amplitude spectrum of PG 1605+072 in the 1000–5000 μHz range. Left panels, from top to bottom: Hβ velocity, Hγ velocity (with no Mount Stromlo data), B‐band photometry, and photometry by Kilkenny et al. (1999) in 1997 May. The dotted lines represent the 10 strongest modes found. The right panels show greater detail centered around 2100 μHz.
