Tables shown in "Field information" are presented as files in this web page.
1. Basic field information and clustering results: each column
is separated by "||". The following information is included in the file.
2. Full clustering results for each field: columns are separated by " |". The format is "field id: the 1st largest cluster id (fraction) | the 2nd largest cluster id (fraction) ...".
Each file has 28 columns: NSVS id, NSVS field name, RA, DEC, median ROTSE mag., mag. scatter, the number of good data points, eight variability indices, cluster id, D_M, Simbad id, Simbad type, WISE id, distance to WISE objects, 2MASS id, distance to 2MASS objects, SDSS id, distance to SDSS objects, GALEX id, and distance to GALEX objects. Columns are separated by "|". The files can be found in this directory. We also provide a single text file of all objects which are included in our analysis and in the current database. The file can be downloaded as a gzip-compressed file: NSVS_catalog.txt.gz (size: 257MB; ASCII file).
