Index of /ogle/ogle2/var_stars/lmc/cep/catalog
This directory contains the distribution of the "OGLE Catalog of Cepheids
from the Large Magellanic Cloud".
***UPDATE***
The LMC Catalog of Cepheids archive was updated on Apr. 24, 2003.
Missing 'B' band measurements were added. Periods and mean magnitudes
were refined based on full set of data collected during the OGLE-II
phase (to the end of November 2000). Also the photometry files in
lmc_sc*/phot/ subdirectories contain now all photometric data collected
to the end of the OGLE-II phase.
***WARNING***
The content of this archive was revised on Apr. 1, 2000 due to revised
calibration of the OGLE photometric data. A small systematic effect in
the original calibration was found, mapped, and applied to the data.
This effect, caused by some scattered light in the instrument resulting
in non-perfect flat-fielding, affected only East/West edges of the
frames and amounted to 0.08 mag in the I-band and 0.05 mag in the B and
V-bands at the very edges of the field. On average the effect was very
small - of the order of 0.01-0.02 mag.
We are very grateful to Dr. D.S. Graff (Ohio State University) for
pointing out to us this systematic effect.

relations.

lmc_sc*.tar -- tar archive containing entire distribution of the Catalog
of the LMC_SC* field.
table1.dat -- names and equatorial coordinates of the OGLE-II fields in
the LMC.
table2.dat -- red clump stars E(B-V) reddening in the LMC fields.
table4.dat -- cross-identification of the same objects in the Catalog.
table5.dat -- number of Cepheids, all stars and stars with I_0 < 17.5
detected in the LMC fields.
---------------------------------------------------------------------------
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:
Hel JD, magnitude, error.
cat_lmc_sc1.ps.gz -- Postscript version of the Catalog of Cepheids
of the field LMC_SC1.
lmc_sc1.tab -- Table with basic data for Cepheids in the field
LMC_SC1. The columns are:
ID number, RA(2000), DEC(2000), P(days), T_0 (HJD) -
2450000, log10(P), I, V, B, B-V, V-I, W_I, E(B-V), I_0,
V_0, B_0, (B-V)_0, (V-I)_0, R_21, \phi_21, Classification.
T_0 corresponds to maximum brightness, magnitudes are
intensity means, colors are differences of mean
magnitudes transformed independently to the standard
system. Magic numbers 9.999 or 99.999 mean "no data".
Any presentation of the scientific analysis or usage of the data from
the Catalog of Cepheids from the LMC should include the appropriate
reference(s) to OGLE paper(s).
