... 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. ...

... I will touch upon the following points: fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
... A Splendid Visit to the Star Hill Inn, New Mexico In November I was fortunate to visit, with my wife Carol, one of the southwest's premier astronomy retreats, the Star Hill Inn north of Las Vegas, NM. ... I spent four nights observing under transparent skies which, when cloud free (one of four nights was pristine while the other three were clear about half the night), revealed magnitude 6.5 stars and, for example, M33 as a naked eye object! ... These efforts should not go unnoticed by AAAP members. ...
