This directory contains OGLE-III maps of 41 Small Magellanic Cloud
fields (SMC100-SMC140) observed during the OGLE-III phase of the OGLE survey. 

REMARK: This a NEW DATASET (Aug 20, 2012), corrected in V and V-I for
        calibration inaccuracy of very red objects (V-I>1.5) due to
        non-standard OGLE-III I-band filter passband, using data from
        OGLE-IV camera, as described in the paper by Szymanski et al.
        (2011), Acta Astron. 61, 83, section 3.2

The directory structure is as follows:

README              - this file
fields.txt          - equatorial coordinates and number of objects found
                      in the OGLE-III SMC fields.
pap.pdf             - PDF version of the paper Udalski et al (2008),
                      Acta Astron. 58, 329, describing the maps.

All *.bz2 files are compressed with the bzip2 utility.

Format of maps in C-language is:

"%6d %11s %11s %7.2f %7.2f %6.3f %6.3f %6.3f %3d %2d %5.3f %4d %2d %5.3f\n"
 
with columns:
                                                 V-band     I-band
DB_no RA(J2000) DEC(J2000) X_ref Y_ref V V-I I  Ng Nb sig  Ng Nb sig

where

DB_no - number in the database,
RA, DEC - equatorial coordinates,
X_ref,Y_ref - pixel coordinates in the I-band reference image,
V, V-I, I - photometry data,
Ng - number of "good" measurements,
Nb - number of "bad" (removed with 5 sigma rejection alghoritm) measurements,
sig - standard deviation of "good" measurements.

WARNING!!! "Magic" numbers: 99.999 for magnitude and 9.999 for color and
standard deviation denote "no measurement". -1 in the N_b V-band column
indicates that the V-band counterpart of an object was found in more
than one subfield and the photometry was merged.


!!! Any presentation of the scientific analysis or usage of the data from
the OGLE-III VI maps of the SMC should cite the apropriate OGLE paper(s). !!!
