These pages provide detailed worked examples of
SDSS data retrieval using the various interfaces provided. In addition, we
provide discussions of how to access and read some of the unusual file
types used in the survey, and perform certain operations, such as
spectra in bulk. This is a variant of the spectroscopic
data set which has extra files per plate: one containing the calibrated
object list entries for each spectrum, and one containing the corresponding
postage-stamp (or "atlas") images.
