PACS spectra of Arp 299 A, showing the detections for CO J = 14−13, 16−15, 18−17, and 20−19. The J = 20−19 transition is only a 2σ detection. The line to the right of the J = 16−15 transition, around 1000 km s^-1 is the OH doublet (Π_1/2−Π_1/2 3/2–1/2 163.124−163.397μm), and the line to the right of the J = 18−17 transition is the [OI] 145 μm line. The velocity scale is calculated for a redshift of z = 0.01030 and the channel spacings are 47, 57, 64, and 140 km s^-1 for the J = 14−13, 16−15, 18−17, and 20−19 respectively.
