Frequency region with HOOH transitions (gray) toward L1551-IRS 5 using position-switching mode. All spectra have the same intensity scale, but (except for the first spectrum) are plotted with an intensity offset. The inset shows the same region around the HOOH transition 41,3 − 30,3 at 143.71263 GHz using frequency-switching mode.
