... ARC 3.5m | NICFPS . ... Taking Exposures . ... As with other IR detectors, it has the capability to be read out non-destructively, allowing for multiple readouts per exposure. In NICFPS, the number of times the detector is read out for each exposure is determined by the Fowler Sampling (FS or NFS, Number of Fowler Samples) setting. ... The NFS=0 mode is somewhat unusual for an IR detector; in this mode, the array is reset, the specified exposure time elapses, and then the detector is read out. ...

Commentaires : The Trifid Nebula (also known as Messier 20 and NGC6514) is an H II region with a remarkable collection of open cluster, emission nebula (the lower, red portion), reflection nebula (the upper, blue portion) and dark nebula (the septation within the emission nebula causing the trifid appearance, also designated Barnard 85). www.astronomica.es . ...

... By undertaking a spectral and photometric investi­ gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...
