... Bit Fields . Bit Fields: Practical Example . ... NOTE: The combination of pointers and bit-level operators makes C useful for many low level applications and can almost replace assembly code. ... To illustrate many points of bitwise operators let us write a function, Bitcount , that counts bits set to 1 in an 8 bit number ( unsigned char ) passed as an argument to the function. int bitcount(unsigned char x) { int count; for (count=0; x != 0; x>>=1); if ( x & 01) count++; return count; } . ...

Visual Discovery of SN 1996bk in NGC 5308. ... Of course we are pleased when we make a discovery, but visually observing galaxies is our real pleasure; supernovae may be the "rational" motive to look at a galaxy. ... Back to science.. ... Some 30,000 observations in four years on a programme of 600 to 800 galaxies (priority is given to the northern ones) have produced two official supernovae, one in 1995 and this one. ... We would like to thank the amateurs directly involved in confirming 1996bk. ...

... ESO, the European Southern Observatory . ... Star Clusters . ... Stars@ESO . ... Some months ago, the ESO Very Large Telescope (VLT) observed a classical dark globule, Barnard 68 (B68) , in front of a dense star field in the Milky Way band. ... Answers to some of these basic questions are now being provided by new and unique observations in the infrared part of the spectrum with the SOFI multi-mode instrument at the ESO 3.5-m New Technology Telescope (NTT) at La Silla. ... Secrets of a Dark Cloud . ...

These routines are meant to supplement the standard C library str* routines Since each version of Unix has a different set of "extra" string functions, this package is meant to bridge the gap, and provides some of the more useful "extras". ... Perform a quicksort on an array of strings. flag st_expr_expand (char *output, unsigned int length, CONST char *input, CONST char *(*get_variable) (CONST char *variable, void *info), void *info, FILE *errfp) . ...

... Planets . ... The planets were found using the HARPS instrument on the 3.6m telescope at ESOтАЩs La Silla Observatory. ... A planet in orbit around a star causes the star to regularly move towards and away from observers on Earth. ... One newly discovered planet, HD 85512 b, is best hope found so far for a habitable exoplanet. ... The HARPS team so far have found that about 40% of stars similar to own Sun have at least one planet smaller than Saturn (which is 95 times more massive than Earth). ...

... Right: Corresponding scan tracks for the same date ( red ) and previous dates ( blue ), which cover about 2/3 of the map area (the field was completed on June 15). ... The I-GALFA survey area is divided into several fields with different declination ranges. ... By starting each subsequent night at a different position, we can cover the entire map area by ``weaving'' many such tracks together to build up a complete image of the sky brightness at all positions in the field. ...

Nova in M31 2000 2 . This page is devoted to information on Nova M31 2000 2 in M31 (= NGC 224) Basic information on this Nova, including the last reported brightness, on this Nova can be found on the main page . Information on the original web pages for many of these images can be found on the Supernova links web page. ... Two of these Novae were announced at the same time, one far past maximum, and the other near maximum. ... LOSS image . ... Remanzacco Observatory image . ... 2 > 18.5 . ...

... There is an opportunity to perform O-C calculations for objects which are absent in the data base of the package. Such objects can be described by orbital elements or by initial coordinates and velocities. ... On pressing Edit file button user has a possibility to look through the list of object elements or their coordinates and velocities to add or to change it. ... For example, the designations of objects in the list can occupy the last position in each line. ...

... It was a great privilege for me to live and work for dozens of years within that scientific and humanist community, especially for sixteen years at PhIAN. ... Mandelshtam began his research at the University of Strasbourg (Germany) with the famous physicist Karl Ferdinand Brown, who was the recipient of the 1909 Nobel Prize in physics together with Guglielmo Marconi for developing wireless telegraphy. ... Mandelshtam's collected works show that he was equally familiar with all the branches of...

... Bad Astronomy . ... On Sunday, March 23 rd , the television "superstation" TBS aired a show called "Fire From the Sky", yet another in a long line of documentaries about imminent doom from an asteroid collision. ... They aren't kidding when they say it's a matter of global life and death, and it's terrible that there isn't enough money being spent on searching for Earth crossing asteroids. ... Like "Asteroid", one of their animations showed a cloud of asteroids very close to each other. ...
