... This article describes the AXAF aspect determination pipeline and its components, and highlights a procedure for determining centroids-a crucial step in deriving the post-facto aspect solution. ... The Ground Aspect Determination System (GADS) pipeline is a collection of tools which process aspect telemetry and generate aspect data products. ... Using a subset of ACA pixel data from the Aspect Interval, we identify poorly-fitting PSFs and find spoiler stars in star and fiducial light images. ...

... This method is called once when the filter is loaded. ... This method should return a flag word that specifies the filters capabilities. ... With CONVERT_TO_FLOAT, the filter is called with the image data converted to a FloatProcessor (3 times per image for RGB images). ImageJ will lock the image before calling this method and unlock it when the filter is finished. For PlugInFilters specifying the NO_IMAGE_REQUIRED flag and not the DONE flag, run(ip) is called once with the argument null . ...
