... Before being able to actually reduce and analyse a new set of observations, the observer has to prepare, sort out and arrange the data. That is, for instance, make a first quality check, classify data according to a set of rules and associate with each science frame a set of relevant calibration frames . This task can be cumbersome because of the complexity of the instruments and the large number and the diversity of the data files they produce. ...

... Intro to HST Data Handbooks 8.0 May 2011 . ... Introduction to the HST Data Handbooks > Chapter 5: HST File Names > 5.4 Associations . ... The ACS, NICMOS, STIS, and WFC3 calibration pipelines sometimes produce single calibrated images from associations of many exposures. ... In this case, the original set of exposures constitutes the association, and the mosaic is the association product . ... In practice, STIS stores the exposures belonging to associations differently than the other instruments. ...

... Early studies of PMS stars focused on T associations, especially Taurus-Auriga. However, one might expect low mass star formation to be different in OB associations. ... He identified Orion OB1a as the stars northwest of the belt. Orion OB1b is composed of the stars near the belt, including the belt stars and Orionis. ... He finds no perceptible distance change within the Orion OB1b association and finds the distance modulus to be 7.8 and 7.9 for Orion OB1a and OB1b respectively. ...

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...

... This is done by taking in all input files the extension whose name is specified by the maintable parameter (called 'merged extension' in what follows) and merging the columns into a single output extension of the same name. ... Its contents is taken from the CCDID keyword (and QUADRANT for EPIC PN). ... To propagate other column specific keywords, they must be specified manually via the extensionchecks , mainattributes , maxattributes and minattributes parameters (see above). ...
