lmc_sc*.tar    -- tar archive containing entire distribution of the Catalog
                  of the LMC_SC* field.

dmod.tab       -- Table with basic data for double-mode RR Lyr stars. The
                  columns are: Field, Star_ID (RA(2000), DEC(2000)),
                  Star number (consistent with published LMC maps), 
                  P1 (days), dP1 (days), P0 (days), dP0 (days), P1/P0, 
                  I, V, B, I_0, V_0, B_0,
                  I-amplitude (FO), V-amplitude (FO), B-amplitude (FO), 
                  R_21 (FO), \phi_21 (FO), R_31 (FO), \phi_31 (FO), 
                  I-amplitude (FU), V-amplitude (FU), B-amplitude (FU), 
                  R_21 (FU), \phi_21 (FU), R_31 (FU), \phi_31 (FU), 

non_radial.tab -- Table with RR Lyr stars which exhibit closely spaced
                  frequencies. The columns are: Star_ID, dominant period, 
                  secondary period, period ratio.

other.tab      -- Table with other pulsating stars.
                  The columns are:
                  Field, Star_ID, Star number (consistent with published LMC
                  maps), P (days), dP (days), T_0 (HJD - 2450000), I, V, B,

                  T_0 corresponds to maximum brightness, magnitudes are
                  intensity means.

overlap.tab    -- cross-identification of the same objects in the Catalog.

rr_in_clusters.tab -- RR Lyr stars in six star clusters in the LMC.
                  The columns are: Star_ID, cluster name, angular distance
                  from the cluster center (arcsec).

---------------------------------------------------------------------------

Catalog of each field has the following structure (e.g. catalog of
the LMC_SC1 field):

subdirectory fcharts  -- finding charts of individual objects; gzipped  
                         Postscript version. The file name is: object_id.ps.gz
                         The finding chart is a 60"x60" part of the I-band 
                         frame, centered on the star. White cross marks the
                         star. North is up and East to the left.

subdirectory phot     -- photometry of individual objects:

    subdirectory  I   -- photometry in the I-band
    subdirectory  V   -- photometry in the V-band
    subdirectory  B   -- photometry in the B-band

                         The file name is object_id.dat.gz in each of these
                         subdirectories. Each file contains 3 columns:
                         HJD, magnitude, error.

lmc_sc1.tab        -- Table with basic data for RR Lyr stars in the field
                      LMC_SC1. The columns are:
                      Star_ID (RA(2000), DEC(2000)), Star number 
                      (consistent with published LMC maps),
                      P (days), dP (days), T_0 (HJD), 
                      I, V, B, I_0, V_0, B_0, I-amplitude,
                      V-amplitude, B-amplitude, R_21, \phi_21, R_31,
                      \phi_31, Classification. 
                      T_0 corresponds to maximum brightness, magnitudes are
                      intensity means.


Any presentation of the scientific analysis or usage of the data from
the Catalog of RR Lyr stars from the LMC should include the appropriate
