Beginning of ReadMe : V/141 Light-Motion Curve Catalogue (LMCC) in Stripe 82 (Bramich+ 2008) ================================================================================ The Light-Motion Curve Catalogue in SDSS Stripe 82 (LMCC) Bramich D.M., Vidrih S., Wyrzykowski L., Munn J.A., Lin H., Evans N.W., Smith M.C., Belokurov V., Gilmore G., Zucker D.B., Hewett P.C., Watkins L.L., Faria D.C., Fellhauer M., Miknaitis G., Bizyaev D., Ivezic Z., Schneider D.P., Snedden S.A., Malanushenko E., Malanushenko V., Pan K. <Mon.

Soc. 386, 887 (2008)> =2008MNRAS.386..887B =2013yCat.5141....0B ================================================================================ ADC_Keywords: Positional data ; Proper motions ; Photometry, ugriz ; Stars, variable Keywords: catalogues ; stars: photometry, astrometry, variables ; Galaxy: stellar content ; galaxies: photometry Abstract: We present a public archive of light-motion curves in Sloan Digital Sky Survey (SDSS) Stripe 82, covering 99deg in right ascension (20.7h to 3.3h) and spanning 2.52deg in declination (-1.26 to 1.26), for a total sky area of about 249sq.deg. Stripe 82 has been repeatedly monitored in the u, g, r, i and z bands over a seven-year baseline. Objects are cross-matched between runs, taking into account the effects of any proper motion. The resulting catalogue contains almost 4million light-motion curves of stellar objects and galaxies. The photometry are recalibrated to correct for varying photometric zeropoints, achieving  20mmag and 30mmag root-mean-square (RMS) accuracy down to 18mag in the g, r, i and z bands for point sources and extended sources, respectively. The astrometry are recalibrated to correct for inherent systematic errors in the SDSS astrometric solutions, achieving 32mas and 35mas RMS accuracy down to 18mag for point sources and extended sources, respectively. For each light-motion curve, 229 photometric and astrometric quantities are derived and stored in a higher-level catalogue. On the photometric side, these include mean exponential and PSF magnitudes along with uncertainties, RMS scatter, chi^2^ per degree of freedom, various magnitude distribution percentiles, object type (stellar or galaxy), and eclipse, Stetson and Vidrih variability indices. On the astrometric side, these quantities include mean positions, proper motions as well as their uncertainties and chi^2^ per degree of freedom. The here presented light-motion curve catalogue is complete down to r 21.5mag and is at present the deepest large-area photometric and astrometric variability catalogue available. Description: The full LMCC catalogue consists of 396 FITS files in the "lmcc" subdirectory, each of these files containing the astrometric and photometric results for the sources in 1 minute of right ascension. The higher-level catalogue consists of 8 FITS files in the "hlc" subdirectory, each containing the 229 photometric and astrometric quantities for the sources in 1 hour of right ascension. The 8 files "hlc_xx.dat" (xx representing the hour of right ascension) represent a "slim" version of the full catalogue, and contain 36 of the 229 parameters for each of the 3,700,548 sources.
