... Given the multitude of units and systems that have been used for infrared (IR) photometry (magnitudes, Jy, W m -2 ?m -1 , erg sec -1 cm -2 ?m -1 , etc.) and given the lack of a standard for ground-based IR filters, NICMOS has adopted the IRAS approach ...
... The temporal evolution of the first and second overtones of CO at 2.29 m (2-0 bandhead) and 1.62 m (6-3 bandhead) and of the (U-B), (B-V) and (J-K) colors are investigated. ...
... on the 24 ЮМm background intensity of 1.9+/-0.6 nW m-2 sr-1 of which the majority (~60%) stems from sources fainter than 0.4 ... sources below 60 ЮМJy contribute 0.8+0.9-0.4 nW m-2 sr-1 to the background, which provides an estimate of the total 24 ЮМm ...
