Magnitudes and Colours

Database Tables
| MBOSS colour database: colour, absolute magnitude, spectral gradient, dynamical class for each object.
| mbossData (ASCII)
| |
The mbossData.txt file is formatted with fixed length columns. "#"
denotes a comment line. The columns are:
- Object: name of the object. 1998WW31+B, +C refer to the
satellites; Warning: measurements reported for the main body (eg
1998WW31) are likely to include measurements of the object together
with its satellite(s).
- Class: dynamic class of the object, using a classification derived from that of Gladman et al, published in SSBN. See the MBOSS-2 paper for details.
LPComet: Long Period Comet
- SPComet: Short Period Comet
- Detachd: Detached Disk object
- Scatter: Scattered Disk object
- Class-c: Cold Classical Disk object
- Class-h: Hot Classical Disk object
- Res-3:2: Resonant object on the 3:2 resonance, Plutino
- Reson.: Resonant object on another resonance.
- JTrojan: Jupiter Trojan
- Centaur: Centaur
- Epo: Number of independent epochs available.
- M11: Absolute R magnitude (not V), normalized to r = Delta = 1 AU, with no attempt to correct any phase effect.
- Grt: Spectral gradient, in %/100nm, spectrum normalized to 1 at V.
- B-V, etc: colours. Other filter combinations are available upon request.
The values listed in the various columns are x/sigma/disp,
defined as follow:
- x is the weighted average of all the available measurements,
obtained as
 | [1]
|
where x_i and sigma_i are the measurements and
error bars published by the individual authors.
- sigma refers to the total error on the average, obtained as
 | [2]
|
where x is the average obtained in [1]. The first term of the
square root refers to the combination of the error bars on the
individual measurements, and the second to the dispersion of the
measurements.
- disp refers to the dispersion of the measurements,
obtained as
 | [3]
|
i.e. is the second term of [2]. The disp of Grt is an
exception; refer to Hainaut and Delsanti 2002.
| | Average colours for each physico-dynamical class.
| mbossClasses (ASCII)
|
|---|
|
For each colour and each class, 3 values are listed:
The number of objects used in the average; the average value, and the
dispersion. M11 refers to the absolute R magnitude; Grt to the
gradient of the reflectivity spectrum, in %/100nm.

The HTML version comes with links to the papers.
In both files, "Counts" refers to the number of measurements included
in the database for that object.

Full list of papers from which photometric measurements were used.
In most cases, a link to the corresponding ADS page is
included. The list uses the A&A mnemonics.
