GALEX- columns
TILE_GALEX, FUV,errFUV , NUV, errNUV : GALEX Tile name and photometry GALEX or EM
** FUV or NUV_MASK : Tell about the nature and quality of the photometry.
NUV_MASK=0 : Analyzed by EM : GOOD SOURCES
NUV_MASK=1 : Not analyzed by EM : MUST BE EXCLUDED
NUV_MASK=2 : EM hand made masks : SHOULD BE EXCLUDED
NUV_MASK=3 : 2+1 : MUST BE EXCLUDED
NUV_MASK=4 : CFHTLS i band masks : OPTICAL “RISKY” AREA (bright stars,...)
NUV_MASK=5,6,7: 4+1 & 4+2 & 4+2+1 : MUST BE EXCLUDED
** FUV or NUV_FLAG : based on the SExtractor ellipses of bright GALEX sources to investigate
if crowding affect the photometry.
NUV_FLAG=0 : EM phot. & outside ellipses of bright sources
NUV_FLAG=1 : GALEX phot. & with no neighbors inside ellipse
NUV_FLAG=2 : EM phot. & inside ellipses of bright sources
NUV_FLAG=3 : GALEX phot. & with neighbors inside ellipse
** FUV or NUV_NFLAG : Flux contribution of neighbors wrt the bright GALEX sources (NUV<21.75)
Both the bright source and the neighbors will share the same NFLAG.
N1 = Number of neighbors with Fneigh/Fgalex < 1/10
N2 = Number of neighbors with 1/10 < Fneigh/Fgalex < 1/2
N3 = " " 1/2 < Fneigh/Fgalex < 2
N4 = " " 2 < Fneigh/Fgalex
Note that Nx<10 so that NFLAG = N1+N2*10+N3*100+N4*1000
ID_ZPHOT , TILE_ZPHOT : Ident ZPHOT catalog and Tile number
INOUT : 0=IN OVERLAP 1=OUT OVERLAP from ZPHOT cat.
ZPHOT, ZPDF : Zphot values
CHI_GAL, CHI_STAR, CHI_QSO, Z_QSO : Chi2 from Zphot analysis
CFHTLS - columns
ID_ORIG , TILE : Ident and Tile number
RA , Dec : CFHTLS coordinates
R2, A_IMAGE, B_IMAGE, THETA_IMAGE, KRON_RADIUS: Half light radius and shape parameters
U,G,R,I,Z : magnitudes corrected for galactic extinction and with offsets from photo-z catalog
errU,G,R,I,Z : mag errors
EB_V : Galactic EB_V
CLASS_STAR , FLAG_U,G,R,I,Z : SExtractor class_star and optical Flag in individual bands
FLAG : 0= Gal, 1=Star, 8=Saturated
Other data - columns
