A sharp contrast is seen between the `crowded' energy map of the modulated oscillations (individual minima and maxima of the signal identified by the Mexican hat wavelet) in section 13 and and the `smooth' presentation of the norm-Morlet transforms of the same data in section 15. ... construct an energy map based on individual events. smooth the map by merging the events that are `close enough' to each other. ...

New Images Hint at Wet and Wild History For Europa . Chunky ice rafts and relatively smooth, crater-free patches on the surface of Jupiter's frozen moon Europa suggest a younger, thinner icy surface than previously believed, according to new images from Galileo's spacecraft released today. ... These features, which lend credence to the idea of hidden, subsurface oceans, also are stirring up controversy among scientists who disagree about the age of Europa's surface. ... Europa . ...

... Future seminars . ... Long -term evolution of 27 days signal in solar activity and terrestrial magnetic indices - common features and differences ". ... The 27-day signal created by the solar rotation is reflected by the 27-day geomagnetic signal. We study the long-term evolution of the 27 days signal and compare its properties for solar and geomagnetic activity. ... We obtain that 'short' and 'long' period in the 27-days range are differently reflected in the solar and geomagnetic activity. ...

The wavelength atlas with a list of about 550 lines has been synthesized from data at center of the Sun ({mu}=1) and at {mu}=0.89, smoothed out over an area of 30 arcsec. ...

. You can display the line by line difference between two files with the diff command. diff file1 file2 . The information given by the command tells you what changes need to be made for file1 and file2 to match. If there is no difference between the files you are returned to the shell prompt . diff indicates which lines need be added ( a ), deleted ( d ) or changed ( c ). Lines in file1 are identified with a ( < ) symbol: lines in file2 with a ( > ) symbol. Examples . Did You Know? .

... Recognition of Anomalous Events S. Monai 1,2 and F.Pasian 2 1 Osservatorio Astronomico di Brera Merate, Italy 2 Osservatorio Astronomico di Trieste, Italy Abstract. We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) ... Raw images, as read from a CCD, are often a#ected by some events which are revealed by anomalous pixel values, i.e., single saturated pixels or pixels at zero intensity (also named hot or bad pixels). ...

However, molecular emission features are only very rarely observed in the optical spectra of PPNe. ... On the other hand, it is well known that cometary nuclei spectra show prominent Swan band emission. In both spectra of IRAS04296 we have discovered strong emission in the (0;0) and (0;1) bands of the Swan system of the molecule. ... Now consider the c
