###############################################################################
This directory contains times of maximum light for the Large Magellanic Cloud
Cepheids derived from the MACHO (1992-1999) and OGLE (1997-2008) data.

The structure of the catalog:
README -- this file.
list.dat -- list of all analyzed Cepheids; it contains in
consecutive columns: OGLE III Catalog of Variable Stars ID (see [1]),
mean period and its error (days), pulsation mode (F or 1O) and remarks
(O - OGLE II data exist, V - MACHO V data exist, R - MACHO R data
exist, A - amplitude is variable in at least on of the data sets).
subdirectory data/ -- contains files OGLE-LMC-CEP-NNNN.max which contain
in consecutive columns: time of maximum light, its error and data
source identification (O, R and V for OGLE, MACHO R_M and MACHO V_M,
respectively). OGLE-LMC-CEP-NNNN is OGLE-III Catalogue of Variable
Stars ID (see [1]).
OGLE-LMC-CEP_max.tar.gz -- tar and gzipped subdirectory data/ . To uncompress
it type:
> gunzip OGLE-LMC-CEP_max.tar.gz
> tar -xvf OGLE-LMC-CEP_max.tar
