Data tables for each individual comet

 

 

Following we present a set of tables with the reduced data for each individual comet. Each data table contains the following columns:

1	2	3	4	5	6	7	8	9	10
r (AU)	HN	Inbound / Outbound	Mag. code	Date	Reported Mag.	Phase	Observatory code	MPC Number	Observer/Observatory Name

1. r (AU) - Heliocentric distance of the comet at the observing time
2. H_N - Reduced Magnitude - V(1,1,0) ( 1 AU from the Sun and the Earth and 0° phase angle)
3. Inbound / Outbound - Position in the inbound or outbound section of the orbit (preperihelion or postperihelion)
4. Mag. code - Magnitude code according to Table 2
5. Date - Date of observation
6. Reported Mag. - Reported magnitude as appear in the source
7. Phase - Phase angle (°)
8. Observatory code - MPC code for the Observatory (only valid for data taken from MPC)
9. MPC Number - Number of the MPCircular from which the data is extracted
10. Observer/Observatory Name - For data taken from specific articles and from CLICC it appears the name of the observer. For data taken from the MPC we just know the name of the observatory.

• CCD - observations taken by professional astronomers using medium- and large-sized telescopes (1.5 m aperture or bigger) with CCDs.
• Roemer - E. Roemer and her collaborators' reports of nuclear magnitudes.
• Scotti nuclear - Observations by J. Scotti reported as nuclear magnitudes.
• Scotti total - J. Scotti's reports of total magnitudes, including those at $r \le 3$ AU.
• Lamy et al. - Observations by P. Lamy and his group made with the HST
• General - Nuclear reports by any other observer not included in the previous groups; most of the observers are amateur astronomers.
• Total - Reports of total magnitudes taken at r > 3 AU by any observer except J. Scotti.

 

Table 2: Symbols and codes used for data points

Observer	symbol	Code
	(pre - empty ; post - full)	pre / post
General	circle -	1 / 2
CCD	pentagon -	2 / 3
Roemer	upward triangle -	4 / 5
Scotti (nuclear)	diamond -	6 / 7
Scotti (total)	square -	10 / 11
Lamy et al.	downward triangle -	12 / 13
Total r > 3 AU	pre - cross -	8
	post - chicken-foot -	9

 

The data

In the following tables the data is sorted in descending heliocentric distance.
