Herschel pacs sensitivity
WitrynaThe PACS is one of three science instruments for ESA's Herschel Space Observatory (HSO, formerly known as FIRST). It operates either as an imaging photometer or an … WitrynaThe PACS faint star sample has allowed a comprehensive sensitivity assessment of the PACS photometer. Accurate photometry allows us to establish a set of five FIR primary standard candidates, namely Ari, "Lep, !Cap, HD 41047 and 42Dra, which are 2–20 times fainter than the faintest PACS fiducial standard (Dra) with absolute accuracy of <6%.
