Query: Correlations among global photometric properties of disk galaxies   Using a two-dimensional galaxy image decomposition technique, we extract
global bulge and disk parameters for a complete sample of early type disk
galaxies in the near infrared K band. We find significant correlation of the
bulge parameter n with the central bulge surface brightness $\mu_b(0)$ and with
effective radius r_e. Using bivar iate analysis techniques, we find that $\log
n$, $\log r_e$ and $\mu_b(0)$ are distributed in a plane with small scatter. We
do not find a strong correlation of n with bulge-to-disk luminosity ratio,
contrary to earlier reports. r_e and the disk scale length r_d are well
correlated for these early type disk galaxies, but with large scatter. We
examine the implications of our results to various bulge formation scenarios in
disk galaxies.
