The directory structure is as follows: README - this file, fields.dat - information on fields studied, events.dat - list of microlensing events analyzed, detection_eff.dat - detection efficiency post_def.dat - posterior samples for default selection criteria, post_ext.dat - posterior samples for extended selection criteria, post_def_add_ob170114.dat - posterior samples for default selection criteria and assuming wide-orbit solution for OGLE-2017-BLG-0114, post_ext_add_ob170114.dat - posterior samples for extended selection criteria and assuming wide-orbit solution for OGLE-2017-BLG-0114. ================================================================================ Byte-by-byte Description of file: fields.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 6 A6 --- Name Name of the field 8- 9 I2 h RAh Right Ascension J2000 (hours) 11- 12 I2 min RAm Right Ascension J2000 (minutes) 14- 17 F4.1 s RAs Right Ascension J2000 (seconds) 19- 21 I3 deg DEd Declination J2000 (degrees) 23- 24 I2 arcmin DEm Declination J2000 (arcminutes) 26- 27 I2 arcsec DEs Declination J2000 (arcseconds) 29 A1 --- OGLEphase OGLE phase: 3 or 4 31- 37 F7.2 d DeltaTime Total time of observations 39- 43 I5 --- Nepochs Number of epochs 45- 50 F6.4 d MedianDT Median time difference between consecutive epochs -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- ================================================================================ Byte-by-byte Description of file: events.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 16 A16 --- Name Event name 18- 19 I2 h RAh Right Ascension J2000 (hours) 21- 22 I2 min RAm Right Ascension J2000 (minutes) 24- 28 F5.2 s RAs Right Ascension J2000 (seconds) 30- 32 I3 deg DEd Declination J2000 (degrees) 34- 35 I2 arcmin DEm Declination J2000 (arcminutes) 37- 40 F4.1 arcsec DEs Declination J2000 (arcseconds) 42- 42 I1 --- OGLEphase Phase of OGLE project: 3 or 4 44- 61 A18 --- EWSid ID on EWS website or "-" if not announced there 63- 67 I5 --- Nepochs Number of epochs 69- 76 F8.5 --- chi2dof Chi^2 per number of degrees of freedom 78- 90 F13.5 --- t0 HJD of minimum separation 92-100 F9.6 --- u0 Impact parameter relative to theta_E 102-111 F10.6 d tE Einstein ring crossing time 113-120 F8.5 --- piEN North component of microlensing parallax 122-129 F8.5 --- piEE East component of microlensing parallax 131-137 I7 --- t0par HJD of parameter reference epoch 139-144 F6.3 mag Ibase Baseline brightness in I band 146-151 F6.3 mag Isource Source brightness in I band 153-158 F6.3 mag IRC Red clump brightness in I band 160-160 A1 --- f_IRC Flag for IRC (1) 162-169 F8.6 --- rho Source radius relative to theta_E 171-178 F8.6 --- e_rho Error on rho (lower value) 180-187 F8.6 --- E_rho Error on rho (upper value) 189-189 A1 --- f_rho Flag for rho (2) -------------------------------------------------------------------------------- Note (1): N = value from Nataf et al.
