\subsubsection{Herschel PACS/SPIRE}
The Herschel Gould Belt Survey (Herschel key program, Andr\'{e} et al 2007) has completed observations of 13 molecular clouds. The data have been made public in the Herschel Science Archive. For the Ophiuchus cloud, the observations were taken in the PACS/SPIRE parallel mode, granting us wavelength coverage over PACS 70/100 $\mu$m and SPIRE 250/350/500 $\mu$m. We processed the archival data in HIPE 10.0.1, using the standard pipeline for extended sources. The calibration of the offset level is done by looking for the faintest region on the maps and subtracting the mean of the lowest flux densities. We check the calibration by comparing the resulting maps to the Planck maps at 857 and 545 GHz. Since the original observation of Ophiuchus is divided into three fields (containing the cluster, the Eastern streamer and the Northern streamer), the three maps are mosaiced together using the Montage package provided by the Infrared Processing and Analysis Center (IPAC).
