On-line data description
------------------------

 pap.pdf - paper Wyrzykowski et al. (2014), arXiv:1405.3134

 PLOTS/ - directory with figures of all classA events and their MCMC models (see fig.10 in the paper for description)

 PHOT/ - directory containing photometry files

 catalogA_basic.table - basic information about the class A events
 
 catalogA-full.table - class A events and their MCMC microlensing parameters 

 catalogB.table - basic information about the class B events

 efficiency.dat - efficiency of events detection, bining 0.1 in log(tE)

 efficiency02.dat - efficiency of events detection, bining 0.2 in log(tE)


----------------------
Format of the catalogA_basic.table

column:
1: event ID: OGLE3-ULENS-nnnn
2: Right ascension, equinox J2000.0 (hours:minutes:seconds)
3: Declination, equinox J2000.0 (degrees:minutes:seconds)
4: OGLE-III field.chip
5: OGLE-III star number within the field/chip
6: cross-match with the OGLE EWS
7: duplicate information: field.chip.starno of other star with the same event due to overlapping fields

-----------------------
Format of the catalogA-full.table.

column:
1: event ID: OGLE3-ULENS-nnnn

3: Declination, equinox J2000.0 (degrees:minutes:seconds)
4: OGLE-III field.chip.star_number
5: t0 - time of maximum, HJD-2450000.0
6: negative error in t0
7: positive error in t0
8: tE - event's time-scale
9: negative error in tE
10: positive error in tE
11: u0 - impact parameter
12: negative error in u0
13: positive error in u0
14: fs - blending parameter
15: negative error in fs
16: positive error in fs
17: I0 - baseline magnitude in I-band
18: negative error in t0
19: positive error in t0
20: chi_squared
21: dof - number of degrees of freedom
22: V - mean V-band brightness
23: error in V
24: cross-match with the OGLE EWS
25: duplicate information: field.chip.starno of other star with the same event due to overlapping fields

----------------------------
Format of the efficiency*.dat files:

column:
1: log(tE) (lower bin value)
2: tE
3: number of events found in given bin in the simulations
4: number of events not found in given bin in the simulations
5: efficiency of detection in given bin 

----------------------------
PHOT directory:

 CLASSA - photometry of events found by the automated pipeline in the original OGLE-III database
 
 CLASSA-OPTIMIZED - optimized photometry of events obtained in new reductions (typically better quality light curves)

 CLASSB - photometry of events found as class B

All photometry files have 3 columns: HJD-2450000, magnitude in I-band,
magnitude error. CLASSA and CLASSB photometry data have magnitudes
averaged nightly.
