... The NICMOS data reduction and calibration pipeline employs file formats and software architecture techniques that are new and different from what has been used for previous HST instruments. This paper describes the FITS file format used for NICMOS data, which includes error estimate and data quality arrays for each science image, and describes the approach used to associate multiple observations of a single target. ... This group of five data arrays is called an image set, or ``imset'' for short. ...

... Four types of galaxy environments are considered: clusters, centers of groups, other places in groups, and the field. ... In order to check whether the mean ages of the stellar populations depend on environment density monotonically, as the hierarchical par­ adigm predicts, in this work I consider four types of environment separately: the cluster galaxies, the brightest (central ) galaxies of groups, the second­ranked group members, and the field galaxies. ...
