1. Determine H0 using a SQL query to LEDA
... SQL | ... Tutorial: determine H0 using SQL queries to LEDA . ... We select in the database all galaxies with known velocity and magnitude and similar to a given template for which we know the distance, the magnitude and the radial velocity. ... We simply have to choose a property which does not depend on the distance, as for example the rotation velocity ( log(vrot) ) and select the galaxies having log(vrot) in a very narrow range around the value for the template galaxy. ... leda@univ-lyon1.fr ...

Scaling relations and intrinsic motions in the interstellar neutral hydrogen clouds . ... Diameters, masses and velocity dispersions of about 7600 HI clouds were determined on the base of HI RATAN-600 Survey in the second and third quadrants of galactic longitudes in 180 degree 100 dg. ... It is shown that other important dependence - velocity dispersion versus cloud diameters, that is found from molecular clouds, in the case of HI clouds is completely absent ( figure 2 ). ... Figure 1. ...

... 1997: . The parameters of the unique solar complex at the RATAN-600 were enhanced. ... A coude-echelle spectrometer of high and very high resolution was designed and manufactured for the 2-meter telescope (Terskol peak) with the simultaneous spectrum registration in a wide wavelength range ( 3500-10000 A ) by the CCD system. The spectrometer has three Schmidt cameras that enable spectral observations with the resolution of R = 45000, 90000, 180000. ... Archive . ...
