The angular distribution of galaxies encodes a wealth of information aboutlarge scale structure. Ultimately, the Sloan Digital Sky Survey (SDSS) willrecord the angular positions of order 10^8 galaxies in five bands, addingsignificantly to the cosmological constraints. This is the first in a series ofpapers analyzing a rectangular stripe 2.5x90 degrees from early SDSS data. Wepresent the angular correlation function for galaxies in four separatemagnitude bins on angular scales ranging from 0.003 degrees to 15 degrees. Muchof the focus of this paper is on potential systematic effects. We show that thefinal galaxy catalog -- with the mask accounting for regions of poor seeing,reddening, bright stars, etc. -- is free from external and internal systematiceffects for galaxies brighter than r* = 22. Our estimator of the angularcorrelation function includes the effects of the integral constraint and themask. The full covariance matrix of errors in these estimates is derived usingmock catalogs with further estimates using a number of other methods.Comment: 64 pages, 31 figures, new version to match that accepted by Ap
