... Near Infrared Camera and Multi-Object Spectrometer Instrument Handbook for Cycle 17 > Appendix D: Techniques for Dithering, Background Measurement andMapping > D.1 Introduction . ... Multiple exposures with small offsets in the pointing of the telescope between exposures are recommended for NICMOS observations. ... It is strongly advised that provision for direct measurement of the background be included in proposals whenever observations at wavelengths greater than 1.7?m are performed. ...

asncombine -- Process and combine images in one or two NICMOS associations asncombine association . ... set to yes to include error planes in co-added images error. background . ... This is useful to use different background subtractions for different images. fheader . set to yes in order to multiply the background by the value of keyword "factor" in the image header. ... Set to yes to use quadrants statistics save in the image header from previous runs of asncombine. regquad1 . ...

... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...

The problem of solar wind data correlation for the observations onboard several spacecraft is very important for three points of view: . ... This problem is studied now in detail by systematic determination of ion flux and ion velocity data correlations by INTERBALL-1 (IKI group), WIND and IMP 8 (both - MIT group). ... Solar wind plasma correlation lengths from IMP 8, WIND and INTERBALL-1. ... Correlation of solar wind observations onboard several spacecraft: INTERBALL-1, IMP 8 and WIND data. ...

The Agile window provides complete control over the Agile high-speed photometer. ... All other parameters are specified as part of the command that starts an exposure sequence. ... To connect the filter wheel controller, issue this command in the command bar at the bottom of the Log window: agile connDev fw . ... To home the filter wheel controller, issue this command in the command bar at the bottom of the Log window: agile fwhome (there must be a filter wheel mounted in Agile for homing to succeed). ...

... This section will deal with obtaining photons within specified regions of an image. Available regions are: Annulus Box Circle Ellipse Field -- entire field Irregular region based on intensity of map... i.e. region defined by contour levels. ... The imcnts task in the xray-spatial package sums the source and background counts in specified regions, and subtracts one from the other properly normalized. ... imcnts* - Find counts in an extended region, after removing an embedded point source . ...
