This was taken from the Gimp Developers mailing list. * width = 768; height = 512 . The PhotoCD format contains several layers of resolution. The smaller ones (listed above) have no real data compression, just a bit of subsampling on the chroma channel, so that readout and display can be very fast even on computers without impressive CPUs. ... This will let you convert the image to ppm format, at which point you can easily mess with it in the gimp. ... Created: August 25, 1996 . ...

. New research shows that tides can play a major role in heating terrestrial planets and create extremely hot conditions on rocky alien worlds that otherwise might be livable. However, tidal heat can also create conditions favorable to life on planets that would otherwise be unlivable. ESO

... Some programs have support for for compression built in; for example, the -gzip ( -z ) option for GNU tar љ pipes the whole backup through the gzip љ compression program, before writing it to the backup medium. ... This means that if the backup is compressed the way GNU tar љ does it, with the whole output compressed as a unit, a single error makes all the rest of the backup lost. ... Compression takes some time, which may make the backup program unable to write data fast enough for a tape drive. ...

We describe a lossless compression program developed for incorporation into the data acquisition system of a 16 CCD drift scan survey. ... Although numerous programs are available for the lossy compression of astronomical images (e.g., White & Percival 1994; Starck et al. 1996), much less work has been published on lossless compression, in particular for online applications (although see Veran & Wright 1994). ...

The luminosity index lambda is calculated according to de Vaucouleurs et al. (1979) , using the luminosity class lc and morphological type t codes: . lambda = (l cc + t)/10 . where lcc is the luminosity class corrected for inclination according to the relation . lcc = l c - (c . logr25) . where logr25 is the axis ratio and c is a parameter depending on the morphological type t . (c = 2.0 for t <=5 and c = 2.0 -0.9(t-5), otherwise) .

A Gaussian wave packet (also known to physicists as simply a wave packet ), is a wave with a Gaussian envelope. Mathematically, a wave packet, g , may be represented: g^_t_c,f_c,(t) = 12 e^-12 (t-t_c)^2 e^j2f_c (t-t_c) + j . ... We like the wave packet to have unit energy. ...
