... Obs., 1974, v.49, p.80-85. The sixty five radial velocity measurements of Cep C (blue visual companion of Cep A) have been obtained. The evidences are give that Cep C is spectral binary. The most probable periods of system are: 0 d ,89986 and 0 d ,46458 . In both cases the -velocity of Cep C is in good agreement with mean velocity of Cep A. It is a strong argument on their physical connection. The secondary component of Cep C may have very low mass (near 0.1 solar mass or less). ...

... We describe image compression based on the pyramidal median transform, introduced as an alternative to the use of a wavelet transform. The use of a multiresolution support allows ``protection'' of astronomical objects in the image. ... We describe an approach to astronomical image compression through noise removal. ... We begin by explaining why transforms other than the wavelet transform are important for astronomical image compression. ... Negative Values. ... The image dimensions were . ...
