... 2008: . ... Getting information about the studied signal in the time-frequency-power measurements allows recording and analyzing the signals, rapidly varying in time. The use of this device facilitates the separation of radio astronomical signals from noise - the registration of a broadband signal, divided into a large number of narrow areas provides the capability to eliminate the distortions, introduced by the interferences stable in frequency. ...

The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

. Figure 3. The SOHO/EIT derotated fixed-difference images with 6-hour time intervals in four channels of 304, 171, 195, and 284 illustrating the dimmings in different-temperature lines for two events of the 1st rotation (October 26, 2003 (a-d), November 4, 2003 (e-h)) and one event of the 2nd rotation (November 17, 2003 (i-l)). In frame d, the difference image with a 12-hour interval is presented because the 284 heliogram belonging to October 26, 19 UT is not available. To the parent page .

Magnitude Scales and Pho­ tometric Systems More than any other aspects of astronomy, the subjects of magnitude scales and photometric systems are encumbered by history. ... Photometric systems represent attempts to define standard band­ passes and sets of standard sources, measured with these bandpasses, that are well­distributed about the whole sky. ... The division is made at a redder wavelength (ё 650 nm) than for the EROS1 system and the EROS2 blue band more resembles the Hipparcos passband. ...
