Below are 3 sub-tables showing the SDSS/2MASS photometry, position, and spectral type of objects as reported in Hawley et. al 2002. The three subtables are divided according to spectral type and source. The first table below gives only objects from the EDR, and all have spectral types of M0-M8. The second table gives all objects M9 or later for which we have new spectra. The third table gives all objects previously discovered in the Sloan Survey for which we have no new observations (see paper for discovery references of these objects). The tables are all formatted in an identical manner; below each column is described.

Column 1: Spectra Name. For the EDR M0-M8 objects, this name is constructed in the form 'fpSpec-plate-mjd-fiber.fits' where the plate, mjd and fiber information identify the location of the spectra within the sloan database. For following objects, the naming convention 'SDSShhmm+ddmm' was used, with the hhmm giving the ra in hours and minutes, and the +ddmm or -ddmm giving the declination in degrees and minutes.

Column 2: RA. The object's right ascension, in decimal degrees.

Column 3: DEC. The object's declination in decimal degrees.

Column 4: r. The object's r magnitude as measured in SDSS imaging. (a negative magnitude in any filter indicates no measurement in that filter)

Column 5: i. The object's i magnitude as measured in SDSS imaging.

Column 6: z. The object's z magnitude as measured in SDSS imaging.

Column 7: J. The object's J magnitude as obtained from the 2MASS second incremental release point source catalog.

Column 8: H. The object's H magnitude as obtained from the 2MASS second incremenatl release point source catalog.

Column 9: K. The object's K magnitude as obtained from the 2MASS second incremenatl release point source catalog.

Column 10: Spectral type. Spectral type as assigned by Hawley and Covey.
