... Data Analysis SAS News What is SAS? ... In practice this means that you cannot safely use a version of cifbuild earlier that 4.1 with CCF constituents issued after 2002-04-15 . ... You can use cifbuild (either 5.2.0 or 5.3.0) to create a cif that is valid for SAS 5.2.0 by setting the parameter analysisdate to be earlier than 2002-04-15T00:00:00 . ... Only two parameters of that task are of relevance here: the observation date and the analysis date . ... Observation date: [yyyy-mm-ddThh:mm:ss] . ...

... After the data from an observation have been received and processed through the STScI pipeline, hardcopy products ( paper products ) are generated which summarize the data obtained. ... Paper products typically summarize the set of exposures that constitute a visit in the Phase II proposal. ... The content of the pages is as follows: . ...

Next: Flagging, Manipulating and Examining Up: Generating Dummy Visibility Data Previous: Making a Fake Observation . If you just want to generate visibilities corresponding to a particular model image, and do not care whether they follow realistic tracks in the uv plane, then im2uv may suit you. Task im2uv simply Fourier transforms an image (whose units should be Jy/pixel) and writes this transform into a visibility dataset. ... IM2UV . ... Normal visibility selection. Only visibilities . ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

Next: Navigation Pre-Observation Products . ... SRT (Space Radio Telescope) Schedule (SRS) File . ... What: GOCG generates the Space Radio Telescope (SRT) schedule file, or SRS file, from current GSTS file. The SRS file has more precise time stamps than long-term schedules, and also designates which GTS will be used when. ... The SRS file also serves as the antenna pointing schedule file, as it describes the planned orientation of the spacecraft (and solar panels) as a function of time. ...

The run progress pages document the execution of Service Mode and Visitor Mode observing runs carried out at the Paranal Observatory. A summary of the run's characteristics is given, as well as a time-stamped list of all Observation Blocks (OB) that were executed until now. ...

EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

RTT150 . ... This search system is designed for generating the necessary information on series of pointings (observations of each source consist of sets of exposures with different filters and sometimes with different exposure times) for observed sources. Search results appear at the separate page as a table with the following data: . DATE - real (not evening!) observations date (in YYYY-MM-DD format); . ... Bin - minimal CCD binning mode (may vary during the observations); . ...
