Description:
The diffuse galactic emission maps at decimeter wavelengths
(408 MHz, Haslam et al., 1982A&AS...47....1H 1982A&AS...47....1H), (1420 MHz, Reich,
1982A&AS...48..219R 1982A&AS...48..219R, Reich & Reich 1986A&AS...63..205R 1986A&AS...63..205R), (2326 MHz,
Jonas et al., 1998MNRAS.297..977J 1998MNRAS.297..977J) have been destriped using the
method proposed by Schlegel et al., 1998ApJ...500..525S 1998ApJ...500..525S. Statistical
and systematic errors have been evaluated for each map. Each map is
presented in two different pixelizations: ECP (Cartesian Projection)
and HEALPix. In the case of HEALPix pixelization (in which the pixel
area is constant), we omitted the (constant) error maps; the
statistical and systematic errors for each map are summarized in the
"Table 2" section below. Synchrotron spectral index and normalization
factor have been evaluated using the three destriped surveys.
Some of the results in this work have been derived using the HEALPix
(Gorski et al., 1999, Proceedings of the MPA/ESO Conference on
Evolution of Large-Scale Structure: from Recombination to Garching,
ed. A.J. Banday, R.K. Sheth, & L. Da Costa, 37).
