Files of data - Meridian transit circle - Bordeaux - 1995-2007
============================================================

The information below provides the description of the files of data in the
directory:
ftp://ftp.imcce.fr/pub/misc/bordeaux/1995-2007

For more information about these data, see the Note Scientifique et Technique 
de l'IMCCE n.89 (http://www.imcce.fr/page.php?nav=en/publications/nst/index.php)

Planets and satellites.
For each of the 11 planets and satellites that we have observed, the observed 
positions and magnitudes are given in 11 specific files with the following names: 
“uranus-data.txt”, “neptune-data,txt”, “pluto-data.txt”, “titan-data.txt”, 
“hyperion-data.txt”, “iapetus-data.txt”, “ariel-data.txt”, “umbriel-data.txt”, 
“titania-data.txt”, “oberon-data.txt” and “triton-data.txt”. 
Each of these files contains 8 columns. 
We give an example with the first 3 lines of the file named “uranus-data.txt”:

  2450707.370159  20 30 27.2007  -19 36 55.959     6.196
  2450709.364575  20 30 16.5251  -19 37 31.030     6.178
  2450711.358998  20 30  6.5329   -19 38  3.773      6.206

The first column gives the Julian date of observation in Universal Time. The 
observed right ascension, expressed in hours, minutes and decimal seconds, 
is provided in columns 2-4. The observed declination, in degrees, minutes and 
decimal seconds is given in columns 5-7. At last, the column 8 provides the 
observed magnitude. 


Asteroids.
The observed positions and magnitudes of asteroids are listed in the file named 
“asteroids-data.txt” which contains 9 columns. We give an example with 3 lines 
extracted from this file:

     6  	11 23   1.1496   16 36 40.496     9.8   2450525.487970 
     7   	  8 25 14.5316   11 38 56.610     9.4   2451620.366929 
     8  	20 15 36.6504  -24 51 55.102     8.8   2451796.378358 

The first column gives the number of the asteroid. The observed right ascension, 
expressed in hour, minute and decimal seconds is provided in columns 2-4. The 
observed declination, expressed in degrees, minutes, and decimal seconds, is in 
columns 5-7. The observed magnitude is presented in column 8. At last, 
column 9 provides the Julian date of observation in Universal Time. 

All these observed positions are given in astrometric topocentric coordinates and 
referred to the mean equator and equinox of J2000. The observed magnitudes are 
provided in the V band. The local coordinates of the Bordeaux Observatory 
(UAI code number = 999) are:
Longitude = 0° 31’ 39” W
Latitude   = 44° 50’ 7” N
Elevation  = 73m.
