... Standard magnitudes can only be computed for the U, B and V filters and hence the only standard colours that can be calculated are U-B, B-V and U-V. An important point to note, is that these standard colours can be computed using the following instrumental colours - U-B, B-V, U-V, (UVW1-U), (UVW1-B), (UVW1-V), (UVW2-B) and (UVW2-V). ... The program loops through these colours and if the relevant instrumental magnitudes are present computes the standard magnitudes and standard colour. ...

... 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. ...

... The absolute flux calibration of NICMOS will be calculated from observations of standard stars with known flux distributions F( ). ... In order to expand the set of IR standard stars in the appropriate flux range for NICMOS, M. Rieke, R. Thompson, and collaborators at the University of Arizona are making photometric observations of solar-analog stars, which will be used to normalize the solar spectrum to the observed IR magnitudes. ... Relative flux references accurate to 1.5% for standard...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... 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). ...

The conversion for image files is given in Table . The START descriptor of a MIDAS image refers to the first pixel and is computed from the values CRVAL and CRPIX for the reference pixel as given in the FITS header. ... Table: Name translation between standard FITS keywords and MIDAS descriptors. ...

... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...

... 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. ...

... The standard lbn cal diode was compared to the standard diode. Using the standard diode value and the insertion loss the lbn cal value was computed every 25 MHz from 1200 MHz to 1600 Mhz. ... After the measurement, the insertion loss from the standard diode to the output of the coupler was measured over the frequency range 1200 to 1400 Mhz. ... The major uncertainty in the measurement is in the standard diode ENR and the insertion loss of the waveguide transition. ... freq [Mhz] . ...

... Using UNIX System Calls and Library Functions . ... To use system calls and library functions in a C program we simply call the appropriate C function. Examples of standard library functions we have met include the higher level I/O functions -- fprintf() , malloc() .. ... For most system calls and library functions we have to include an appropriate header file. e.g. stdio.h, math.h . ... Information on nearly all system calls and library functions is available in manual pages. ...

. To redirect the standard output from a command use the > (greater than) symbol followed by the name of the output file. If the file that you redirect standard output to does not already exist it will be created. For example: grep Smith /etc/passwd > popular . This redirects the standard output from the grep command so that it goes to the file popular . This file will contain all occurrences of the string Smith that were found in the /etc/passwd file. **Caution** . Did You Know? .
