subdirectories lmc_sc*/         - the data of the ellipsoidal and eclipsing
                                  red giants in the field LMC_SC*

subdirectories lmc_sc*/fcharts/ - finding charts of individual objects;
                                  gzipped Postscript version. The file
                                  names are: 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.

subdirectories lmc_sc*/phot/I/  - I-band photometry of individual objects. 

subdirectories lmc_sc*/phot/V/  - V-band photometry of individual objects. 

subdirectories lmc_sc*/phot/B/  - B-band photometry of individual objects. 

                                  The file names are: object_id.dat.gz.
                                  Each file contains three columns: HJD,
                                  magnitude, error.

files lmc_sc*/lmc_sc*.ell       - Tables containing basic data of the
                                  candidates for ellipsoidal red giants
                                  in the field LMC_SC*

files lmc_sc*/lmc_sc*.ecl       - Tables containing basic data of the
                                  eclipsing variables in the field LMC_SC*

                                  The columns in the tables are as follows:
                                  star ID, star number (consistent with
                                  published LMC maps), RA (J2000), DEC
                                  (J2000), P (days), T_0 (HJD), I, V, B,
                                  larger I-band amplitude, smaller I-band
                                  amplitude, remarks.
                                  Remarks: U - uncertain, E - eccentric
                                  orbit, LMC_SC* - the same star in the
                                  field LMC_SC*.

files lmc_sc*.tar               - tar archive containing all data from
                                  the subdirectory lmc_sc*.
