We present the Sloan Low-mass Wide Pairs of Kinematically Equivalent Stars(SLoWPoKES), a catalog of 1342 very-wide (projected separation >500 AU),low-mass (at least one mid-K--mid-M dwarf component) common proper motion pairsidentified from astrometry, photometry, and proper motions in the Sloan DigitalSky Survey. A Monte Carlo based Galactic model is constructed to assess theprobability of chance alignment for each pair; only pairs with a probability ofchance alignment </= 0.05 are included in the catalog. The overall fidelity ofthe catalog is expected to be 98.35%. The selection algorithm is purposelyexclusive to ensure that the resulting catalog is efficient for follow-upstudies of low-mass pairs. The SLoWPoKES catalog is the largest sample of wide,low-mass pairs to date and is intended as an ongoing community resource fordetailed study of bona fide systems. Here we summarize the generalcharacteristics of the SLoWPoKES sample and present preliminary resultsdescribing the properties of wide, low-mass pairs. While the majority of theidentified pairs are disk dwarfs, there are 70 halo subdwarf pairs and 21 whitedwarf-disk dwarf pairs, as well as four triples. Most SLoWPoKES pairs violatethe previously defined empirical limits for maximum angular separation orbinding energies. However, they are well within the theoretical limits andshould prove very useful in putting firm constraints on the maximum size ofbinary systems and on different formation scenarios. We find a lower limit tothe wide binary frequency for the mid-K-mid-M spectral types that constituteour sample to be 1.1%. This frequency decreases as a function of Galacticheight, indicating a time evolution of the wide binary frequency. [See text forfull abstract.]
