... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

... While Sfit accepts input from "stdio", it is more natural to save/edit commands in a file (eg "solve_input.sfit") and run the code simply by entering > Sfit solve_input.sfit [linelist] . ...

... Many scientific institutions maintain bibliographies of articles published by their scientists and monitor references made to these publications; these figures are often used to evaluate the effectiveness of the institution. ... a) Identification of papers that are based, at least partly, on new data Publications based on observations can be subdivided into two groups: those presenting new, previously unreported data, and those that make use of already published data. ...

Calculation of Atmospheric Emission Measured by Gregorian Feed Horns Paul F. Goldsmith September 16, 2001 As we use higher frequencies, emission from the Earth's atmosphere becomes more sig- ni cant. ... To use this program, you input the altitude, temperature, and precipitable water vapor (pwv) in mm. ... I have run the ATM code for several values of pwv with plausible temperature, and generated the zenith sky temperature as a function of frequency between 1 and 15 GHz. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... Early studies of PMS stars focused on T associations, especially Taurus-Auriga. However, one might expect low mass star formation to be different in OB associations. ... He identified Orion OB1a as the stars northwest of the belt. Orion OB1b is composed of the stars near the belt, including the belt stars and Orionis. ... He finds no perceptible distance change within the Orion OB1b association and finds the distance modulus to be 7.8 and 7.9 for Orion OB1a and OB1b respectively. ...

... Torsten: How is the SHARE activity different from pipeline improvement going on in the instrument groups? ... We could have different pipelines for different purposes; or merge pipelines with very similar purposes (e.g. WF3 data could be calibrated in an ACS pipeline). ... Mark: We could use Sloan or radio source catalogs to get absolute astrometry (a very high priority SHARE recommendation). ... Discussion: catalogs, pros/cons, community use, is it useful? to whom? for how much of the data? ...

spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...

Why Stars Twinkle . ... Credit Copyright: Applied Optics Group ( Imperial College ), Herschel 4.2-m Telescope Explanation: This is what a star really looks like from the surface of the Earth. To the best the human eye can see, stars are so far away they appear the same as would infinitesimal points of light. ... Because the atmosphere is always windy and changing, the number and position of images is always changing, with the result that stars appear to twinkle . ... NASA Official: Jay Norris. ...
