... A detector map is used to provide a grid of positions over which to calculate and flux weight the ARF. The default detector map is 'flat' which has a weighting of 1.0 for each detector map pixel and is rectangular having sides which just encompass the region specified in the DSS. Only detector map pixels falling within the source region are included in the ARF calculation, e.g. for a circular source box, the pixels in the corners of the detector map will be ignored. ... flat : . ...

After providing on-the-fly re-calibration of HST data to archive users, ST-ECF has embarked on a new project aiming at grouping, cosmic ray cleaning and drizzling images taken by most HST instruments. ... The production of the missing jitter files combined with the extraction of additional engineering parameters will greatly enhance the homogeneity and the scientific value of the entire archive. ... 1995, HST Data Handbook, STScI, 107 . ...

CIMA configuration files offer You a conveniant way of saving CIMA set-ups to files. ... Then instead of making this selections interactively when You are observing, You can just load and apply the configuration files. ... Any other set-up will be ignored! ... In that case, You are forced to use the 'Load only' option to load the configuration file, inspect the selected set-up carefully, apply the set-up (with the 'Accept' or 'Apply' buttons) and then save a new version of the configuration file. ...

... The visibility datasets possibly contain correlations for different polarizations and Stokes parameters. There are two basic ways that polarization characteristics can be measured: firstly, two orthogonal feeds can be present on the antennas, and the four different polarization correlations from a baseline can be taken and recorded. ... There are two ways the user can determine which polarizations he or she wants to process, either with the select parameter, or with the stokes parameter. ...
