This dataset contains over 1.5 million galaxies, +230,000 quasars, and 670,000 stars covering 14,500 square degrees of the sky. +<P> + +Queries by position may be done using either a resolvable object name or an +explicit (RA,Dec) position given in ICRS decimal degrees. The <I>-P</I> flag +can be used to specify the position as a single argument. The default query +size is 0.25 degrees and may be changed using the <I>-s</I> flag. If the +DR8 release of the dataset is desired the <I>-R dr8</I> option may be used, +by default the task will use whichever data release is deemed 'current' y +the service (DR9 as of this writing). Spectra may be limited to a selection +of just 'galaxy', 'qso' or 'star' objects using the <I>-t</I> option. The +<I>-z</I> option may be used to constrain the search by range of redshift +values. +<P> + +Unless otherwise modified, the task will automatically download FITS spectra +for all objects within the query region. The <I>-m</I> flag will print the +positions of each object found (e.g. for marking an overlay), the <I>-u</I> +flag will print the access URLs for the spectra. In the case of position +metadata the FITS files must actually be downloaded to the local machine +since the service doesn't provide this in a query return, the <I>-D</I> +flag will delete these images after the information is obtained. +<P> + +To broadcast the spectra to SAMP-enabled applications using the +<I>spectrum.load.ssa-generic</I> message type, the <I>-S</I> option may be used. +The spectrum may be broadcast as a <I>table.load.FITS</I> message by specifying +the <I>-T</I> flag. +<P> +<A NAME="lbAF"> </A> +<H2>REFERENCES</H2> + +This task is based on the API available from +<P> +<PRE> + <A HREF="http://api.sdss3.org/">http://api.sdss3.org/</A> +</PRE> + +See the documentation at this site for additional information about +parameters.
