SEDs used in photz programme

The seds used in the photometric redshift programme are given as sed***.dat for
6 galaxy and two AGN types in free format, with two numbers per line:  -log10{lambda(micron)} and 
log10{f_lambda(arbitrary units)}.

     
     
BRIGHT NEARBY UV GALAXIES

localuv.ps contains the paper 'Quantifying dust and the ultraviolet radiation-density
in the local universe', accepted by MN

The file psczrRSA.dat consists of 2963 galaxies which are in the PSCz catalogue (Saunders et al 199x)
and which satisfy Vo < 5000 km/sec, and m_pg <= 14.

The format is RA(i8), DEC(i8), l(f8.3), b(f8.3), 4 IRAS fluxes in Jy (4f8.2), 1x, 4 PSCz flux-quality
flags (4i1), name (a10), m_pg(f8.2), diam in arcmin (f5.1), V_hel (i8), lg uv flux (f6.2), reference
for uv flux (i2)

The file psczrRSA2.dat is the subset of 215 of these galaxies for which 2000 A uv fluxes are 
available.

The format is RA(i8), DEC(i8), l(f8.3), b(f8.3), 4 IRAS fluxes in Jy (4f8.2), 1x, 4 PSCz flux-quality
flags (4i1), m_pg(f6.2), diam in arcmin (f5.1), V_corr (i8), lg uv flux (f6.2), reference,
lg S(60) (f7.2), name (a10), lg Halpha flux (f5.2), ref for Halpha data (i2), for uv flux (i2)
V_hel (i8), E(B-V)1, E(B-V)2 (2f6.2)

[ units of uv flux are lg(W/m^2) + 12 ]

[ E(B-V)1 calculated assuming all fir emission is cirrus, E(B-V)2 calculated after
subtracting off optically thick starburst component from 60 and 100 mu fluxes]

[V_corr is velocity corrected for peculiar motion using model of Rowan-Robinson et al 2000]

[uv refs: 1 = Donas et al 1987, 2 = Meurer et al 1995, 3 = Derhaving et al 1994, 4 = Kinney et al 1993]
[Ha refs: 1 = Young et al, 2 = Kennicutt, 3 = Buat et al 1987]
