Version 00 contains Steve Preston's occultations that meet the following criteria:
	- Dates are in 2017.
	- 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
