... When I display the weight map generated for my final drizzled image (or any of the single drizzled images as well), there seem to be representations of the objects in my science image. ... Most likely you need to refine the parameters that are set during the driz_cr step which detects cosmic rays in each of your science frames. ... I've calculated refined offsets between my science images but when I supply MultiDrizzle with the delta shifts the final image is not aligned properly. ...

... The eboxdetect task has two different modes of operation: (1) local detection and (2) map detection. eboxdetect is first run in local mode. The local mode source lists serves as input for task esplinemap which creates background maps (one per energy band for each EPIC instrument) which are then used to run eboxdetect in map mode. ... In both modes, source searching is only performed in the area of the images which is marked by an optional detection mask created by task emask . ...

... Three different techniques for averaging have been introduced. ... The average functions mentioned above will normally produce a result frame whose world coordinates are the intersection of the father frames' world coordinates. ... Averaging statistically consistent values --- љ This command differs somewhat from the purely mathematical functions of the previous two commands in the sense that it tries to anticipate some of the astronomical content of the input data frames. ...

Part of the table and a cartoon figure of the track calculated for the default set of the initial parameters are shown in Fig. 1 and 2. In the future, we intend to made available calculations of a large number of binary systems assuming different intial distributions, chemical composition, etc., to construct a "Galaxy at will", as well as various interface facilities. ...

... 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. ...

... Data . AAS 221 . AAS 219 . ... The first thing to note is that Twitter does not guarantee to return all matching Tweets, whatever method is used (unless you have direct access to their "fire hose", which I don't). ... This should result in the same results as my REST-based search (method 2), since the volume of Tweets was probably not enough to cause this site to miss Tweets based on their collection strategy . ... A search for the tag #aas219 (case insensitive) using the Twitter REST API . ...

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 . ...

Some recent results ( see ) attracted the attentions of astronomers working on field which could benefits from photon counting techniques with high speed and spatial resolutions as adaptive optics. ... Fasti has been designed to be fast and largerly configurable. ... The data rate attined in the best case (30 Mhz), give no impossible load to the digital acquisition in the photon counting mode, since data are 1 bit only, they can be parallelized, giving a maximum speed of about 940.000 32 bit word/sec. ...

... Status of the numerical solutions and validation 2. ... Coupling of "solid" Earth components, e.g. core ­ mantle (Dehant et al.) ... Consistent relativistic formulation of Earth rotation (Gerlach, Klioner, Soffel) Status of the numerical solutions - 2 · The results from numerical solutions suffer from ­ Simplified solid Earth models ­ Incomplete Earth system models or neglecting of certain parts or neglecting of certain coupling mechanisms ­ Methodological limitations of computations...
