... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...

... A baseline vector is oriented from telescope 1 to telescope 2, i.e. the baseline coordinates are the coordinates of station 2 minus the coordinates from station 1. In the aperture plane, the coordinate increases to the East, and the coordinate increases to the North. ... In PEARL, a map on the sky is allocated with the -coordinate corresponding to RA, which increases to the left (East). The relationship between visibility and map is then . ...

... Posts tagged ?point pattern analysis? ... There are three distinctive subjects in spatial statistics: geostatistics , lattice data analysis , and spatial point pattern analysis.

3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...
