ta
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
