List of companions found. The sources not listed here, but represented by reduced data products, were seen as apparently single sources. ===================================================================== owner = PI name ID = object identification name = an internal naming system used in data reduction date = UT date of the observation wav = central wavelength of the filter in nm rho = separation in arcseconds theta = position angle from the brighter target to the fainter companion, measured from North through East B/A = ratio of the flux of the fainter source relative to the brighter source delm = magnitude difference based on B/A see = a seeing estimate in arcseconds FWHM rho*see = product of angular separation and seeing FWHM in arcsec^2 notes = for individual objects, see notes at bottom owner ID name date wav rho theta B/A delm see rho*see notes --------------- --------------- ------------ ---------- --- ------ ------- ----- ---- ---- ------- ----- HOWELL eps_Cet h111000_f1b 2019-09-12 562 0.100 27.613 0.497 0.76 0.93 0.093 a HOWELL eps_Cet h111000_f1r 2019-09-12 832 0.109 29.499 0.298 1.32 0.88 0.096 a HOWELL 46_Tau h112001_f1b 2019-10-16 562 0.084 132.092 0.445 0.88 0.83 0.070 HOWELL 46_Tau h112001_f1r 2019-10-16 832 0.087 132.549 0.502 0.75 0.77 0.068 Notes: ------ a = The quadrant of the position angle is ambiguous, meaning that it could be off by 180 degrees. Here, when possible, the quadrant deemed most probable is selected. b = A difficult fit or one with a goodness-of-fit that is difficult to judge due to faintness, artifacts or other conditions. Here the measurements may be more uncertain than typical. The delta-magnitude is the most difficult measurement.
