To improve the efficiency for the selection of BCGs among the second priority candidates we introduced additional selection criteria using the APM (Irwin [ 1998 ]) database. ... The second priority candidates classified as BCG/H II based on their slit spectra all have rather blue colours according to the APM database (APM ). ... One BCG of the four newly found is classified in the APM as stellar. ...

According to the # 7.1. of the Acting Statutes/Regulations on the International Astronomy Olympiad there should be an Authorized National Representative (Astronomical) Organization (ANRAO) in every participating state: A national astronomical society, a department (section) of the EAAS or IAU in the state, a leading observatory, an astronomical department of a leading university, a ministry of education or another appropriate competent institution. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

So you have downloaded the latest super-duper, all-doing, nice-looking plug-in for The Gimp, but you don't know how to actually plug it in. ... If your plug-in is one which does not require libraries other than libgimp (The Gimp's plug-in library) and libc (the standard C library; most C programs need this), that's all there is to it. ... To avoid having to add an entry for each new plug-in which requires the math library, you can look for the lines in the Makefile which look like this: . ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ... Several trajectories of this type are determined. ... Ivashkin V. V. On optimal trajectories of space flight to the Moon in the Earth--Moon--Sun system. ...
