... Abstract Return the value of the smallest (negative) number representable in a SpiceInt variable. ... Detailed_Output The function returns the value of the smallest (negative) number that can be represented in an SpiceInt variable, where SpiceInt is a typedef defined in SpiceZdf.h. The returned value will be less than or equal to -2147483647. ... Particulars The typedef SpiceInt is used throughout the CSPICE API to refer to integers; the precise type of integer is platform-dependent. ... Files None....

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

New RRC variables with an additional non-radial pulsation . PZ, vol. ... We present a new study of 14 known RR Lyrae variable stars from the Catalina surveys periodic variable star catalog. ... New Double-Mode RR Lyrae Variables III . ... We present a new study of 123 known RR Lyrae variable stars from the Catalina surveys periodic variable star catalog. ... According to these data, the stars are double-mode RR Lyrae variables, pulsating in the first-overtone and fundamental modes. ...

... We present a proposed standard for data dictionaries associated with catalogs being accessed through the Astrophysics Data System (ADS) Mosaic Catalog Service. Each catalog made available for searching must have a data dictionary, which consists of a set of specified keywords describing format, content and location of data. ... There are two keywords in the Table Data Dictionary which indicate to the server software that the corresponding column contains special attributes. ...

This section of library contains information about "classic" Star Catalogs. ... For a Henry Draper Catalog 272149 stars have received a total of 531,211 identifications in 7 сatalogs: . 270456 - in Astrographic Catalogue ( "Carte du Ciel", 4M), . 251943 - in Guide Stars Catalog (GSC), . ... A file with information on the components of 1788 of multiple systems in catalog HDEC (3681 component, or a combination thereof, with 4054 recording). ... A file with information about 21971 variable stars. ...

... The material in "From Stargazers to Starships" meets several important requirements of the national standards. Pages cited below are from National Science Education Standards National Academy Press, Washington 1995. ... For example: the sections on astronomy not only describe calendars and sundials (including their construction), but also the astronomy of the ancient Greeks, including two different ways in which ancient Greeks estimated the distance to the Moon. ...

Next: Modifying Visibility Datasets Up: Flagging, Manipulating and Examining Previous: Plotting Visibilities . There are a variety of variables associated with the dataset that you may like to examine. For example, you may like to plot the system temperature as a function of time; it is usually stored as a variable (the visibilities are variables too). ... After finding out the name of the variable of interest, you can plot it with varplt . ... VARPLT . ... Put variable time on x-axis . ...

... a set of permissions associated with every file and directory that determine who can read it, write to it, or execute it. Only the owner of the file (or the super-user) can change these permissions. a mathematical term that refers to a number, character or word which changes the action of the command it is applied to. a standard code used for representing information on computer systems and networks. It uses the printing and non-printing characters that can be generated by the keyboard. ...

The Apache HTTP Server provides a mechanism for storing information in named variables that are called environment variables . ... For additional flexibility, the directives provided by mod_setenvif allow environment variables to be set on a per-request basis, conditional on characteristics of particular requests. ... As discussed above, the environment passed to CGI scripts includes standard meta-information about the request in addition to any variables set within the Apache configuration. ...

... Standard Commands . ... TwistedActor.Actor is core code for writing an actor: an instrument control computer (ICC) or hub-based script that does something useful. This manual describes the standard commands and keywords that any actor based on TwistedActor.Actor will support. All actors based on TwistedActor typically support the following standard commands (plus additional device-specific commands documented in that actor's manual). ... Connect one or more devices (if not already connected). ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...
