Instrument Science Report OSG-CAL 98-01 NICMOS HISTORY DATABASE AND WEB TOOLS C. Tullos April 10, 1998 ABSTRACT The history of NICMOS platescale, focus, and coronographic hole data has been stored in a database which is accessible via tools on the World Wide Web. ... The Database and Data A convenient way of keeping a history of some of the NICMOS instrument parameters is to put it all in a database, and build web tools to access it. Each dataset is associated with a unique date. ...

... Retrieve the list of all available HK parameter validity ranges for instrument EPN from the CAL and construct a GTI data set with name hkgti_epn.ds : hkgtigen instrument=epn withgtiset=true gtiset=hkgti_epn.ds . ... As 1. but do not consider any present validity ranges for parameters P1 , and P2 : hkgtigen instrument=epn withparameters=true except=true parameters="P1 P2" \ withgtiset=true gtiset=hkgti_epn.ds . ... IN [10,20]"\ withgtiset=true gtiset=hkgti_epn.ds . ...

... Apache HTTP Server Version 2.4 . ... Session encryption support . ... session_crypto_module . ... The session will be encrypted with the given key. Different servers can be configured to share sessions by ensuring the same encryption key is used on each server. ... The SessionCryptoPassphrase directive specifies the keys to be used to enable symmetrical encryption on the contents of the session before writing the session, or decrypting the contents of the session after reading the session. ...

Databases (NSDC) of the Natural Planetary Satellites. ... NSDC: Database of astrometric observations of Natural Planetary Satellites . ... They are thoroughly looking for observations in different sources, creating their owndatabases which are then mostly inaccessible to other researchers. ... In the file "content" with explications, the reference is given to the data source as well as the bibliographic reference. ... Data sources. ... Why a specific bibliographic database for Natural satellites? ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

... LEDA has been the first Extragalactic Database. ... select pgc, objname, al2000, de2000 where de2000 > 76 and al2000 < 1 . select pgc, galaxy_name, al2000, de2000 where de2000 > 76 AND al2000 < 1 . ... For each parameter the method of the calculation (or the definition) is given in the Third Reference Catalogue (de Vaucouleurs et al., 1991) and/or in Paturel et al. (1997) and/or in some additional references given below. ... de Vaucouleurs et al., 1991, 1997 . ... 1995 ; Paturel et al., 2000 . ...

... This section gives a brief description of each of the parameters available to SCHED that are specifically for VLA observations or are especially useful for VLA observations. ... Should be provided for non-VLBI observations. ... This used to be required in order to obtain calibration data for the VLBI observations. ... FREQ: and DOPPLER Warning -- these parameters cannot be used for non-VLBI observations at the VLA since they are only used to adjust the baseband converter frequencies. ...

Up: Sky Surveys . ... The object catalogue and compressed pixel data are stored online and are accessible via the WWW. ... small area (up to 15arcmin) pixel images with attached object catalogue, . ... The primary data format is FITS for both images and binary tables of object catalogues, which enables porting of the data into established software packages. ... In this way, it is possible to browse the data by clicking on objects in the image display or the catalogue list to highlight them in both. ...

. Our introductory notes briefly describes the primary parameters of real scatterers, their basic models and methods of realization of the models. As an example, the models used in astronomy are overviewed. Our table after its completement will show a list of the most popular scatterer models and their parameters (under construction).
