Version 00 contains Steve Preston's occultations that meet the following criteria: - Dates are in 2015. - All asteroids either have a satellite or are resolvable or are USA lower-science events. Three versions of the occultation table are provided: - US-only (occult_us_v10.html) - non-US (occult_non_us_v10.html) - all (occult_v10.html) Date-sorted versions of all three tables are also provided. In addition, non-html versions of the raw data are provided for import into Excel (drop ".html" from the filenames). Each table contains the following fields: DATE_TIME Date and time of the occultation in UNITY date format (MM/DD/YYYY HH:MM) DOW: Day Of the Week (first three letters, i.e. Sun, Mon, Tue...) in London (GMT). Note that nights are split into Sun/Mon, Mon/Tue, etc... AST: Asteroid number AST_NAME: Asteroid name SAT: 1 = Asteroid has a satellite 0 = no satellite RSV: 1 = Asteroid is resolvable with AO 0 = Asteroid is not resolvable with AO ASTER_DIAM: From Horizons, the asteroid's diameter (units = KM) SPECTYPE From PDS, taxonomy from Bus/Binzel 2002 SMASSII survey. ROTPER From the IAU Minor Planet Center Lightcurve Database, the asteroid's rotational period (units = hours). ANG_DIAM: From Horizons, the asteroid's angular diameter (units = arcseconds) SES: The number of times we have observed this asteroid. (note: some sessions may not be useful due to weather, other sessions may be part of RAP, Resolved Asteroid Program) RAP: The number of potential Resolved Asteroid Program sessions (note - some RAP sessions may not be useful). DAMI: "1" indicates the asteroid is on the DAMIT mass priority list. IOTA: "1" indicates the asteroid is on the IOTA modeling priority list. Mdeg: From Horizons, the target-observer-Moon angle (lunar elongation, units = degrees). Mpct: From Horizons, the Moon's illumination (phase, units = percent). STAR_NAME: Star Name. VMAG: Star visual magnitude verified in UCAC4 (Vmag, used for evaluation only if RMAG field is empty). RMAG: Star Red magnitude (rmag) from UCAC4 via VizieR site. dMAG: Drop in star magnitude due to the occultation. DURs: How long the occultation will last, approximately (units = seconds) PATH_ERR: Path/track error offset (units = track widths) LOCATION: Significant land masses where the occultation can be viewed SCI: Second crude attempt at a SwRI prioritization (this may still change later): 3 = RAP (even if the number of prior RAP sessions = 0) 2 = non-RAP but is Trojan or has satellite 1 = No trojan or satellite or RAP, and has been observed before (SES > 0) 0 = No trojan or satellite or RAP, and has not been observed before (SES = 0) PATH: A grading of the path quality based upon path-widths of error (PATH_ERR): 3 = PATH_ERR < 0.3 2 = 0.3 < PATH_ERR < 1.0 1 = PATH_ERR > 1.0 Note: A poor rating could mean that better astrometry is needed. STAR: Star quality approximation: 3 = Bright star (MAG < 10.5), good mag drop (dMAG > 0.5), normal star 2 = Either the MAG or dMAG is iffy (10.5 < MAG < 11.5, 0.5 < dMAG < 1.0) 1 = Both the MAG and dMAG are iffy (10.5 < MAG < 11.5, 0.5 < dMAG < 1.0) 0 = MAG is bad (>11.5), dMAG is bad (<0.5), or double star (currently we don't down-weight other star issues) MOON: Moon quality approximation (note - some values may need adjustment): 3 = Star's lunar elongation > 50 degrees 2 = Elongation < 50 degrees, but dim Moon (Mpct < 50) or bright star (MAG < 10) 1 = Elongation < 50 degrees, but bright Moon (Mpct > 50) or dim star (MAG > 10) 0 = Elongation < 50 degrees, bright Moon (Mpct > 50) and dim star (MAG > 10) SUN: Subjective rating of dusk/dawn at the best observing location 3 = dark 2 = within 3 hrs of sunset or 1 hr of sunrise 1 = twilight conditions 0 = daylight, forget it LOC: Subjective rating of LOCATION: 3 = Visible from continental USA or Europe 2 = Visible from another location that is somewhat accessible 1 = Visible from a poor-access location 0 = forget about it, only the dolphins will view this one WTHR: Subjective rating of seasonal weather at the best observing site: 3 = No weather issues foreseen 2 = Iffy weather, perhaps a cold winter location or dusty in the summer 1 = Severe weather concerns, or concerns due to minimal locations (i.e. FLA-only) ELEV: Subjective rating of elevation at the best observing site: 3 = Greater than ~45 degrees 2 = Between ~15 and ~45 degrees 1 = Less than ~15 degrees DUR: Occultation duration: 3 = DURs > 20.0 2 = 1.0 < DURs < 20.0 1 = 0.5 < DURs < 1.0 0 = DURs < 0.5 RSRC: Subjective rating of our ability to deploy sufficient resources (3=good, 1=poor) COST: Subjective rating of the relative cost of the observations (3=best, 1=expensive) RISK: Subjective rating of our odds of success (3=good, 0=no_way) Q: Sorting field, currently (LQ+PRI+SQ+MQ)*8, can be set by hand FIN: Finalist selections by SwRI, based on all known criteria (above). y = yes, this is a good finalist candidate ? = maybe, this might be a finalist pending more analysis n = no, this occultation won't work COMMENTS: Comments LINK: Hypertext link to the occultation event page on Steve Preston's website _: Always blank
