Lightcurve Parameters Submission Page

Use this page to:

Submit the summary results of your observations. These summaries will be posted to the site for reference by others.
This site is not an official clearing house for observations. Placing your results does not constitute "juried publication". However, by posting your summary, you help other observers to know which asteroids have already been worked or may need further follow up.

If the data being submitted was the result of a collaboration, then enter one record per observer and use the comments field to note the other observers by their observatory code or name.

Explanation of Quality Parameters

  1. Result based on fragmentary lightcurve(s), may be completely wrong.

  2. Result based on less than full coverage, so that the period may be wrong by 30 percent or so. Also used to indicate cases where an ambiguity exists as to the number of extrema between lightcurves (hence the result may be wrong by an integer ratio), and when there is a bare minimum of full-period coverage, i.e., an additional runs are required to increase the accuracy and precision of the derived period.

  3. Secure result with no ambiguity, full lightcurve coverage.

  4. In addition to full coverage, denotes that a pole position is reported.

You should be conservative in your estimate for the Quality parameter. For example, a '3' requires you have more than just complete coverage but that you have data spanning a sufficient number of rotations and covering the majority of the curve at least twice so as to remove any ambiguities with as much certainty as possible. 

 

IMPORTANT NOTE
All lightcurve periods should be reported in hours and should be for one complete revolution. Typically, this means the time for a double min/max cycle to occur.

You are strongly encouraged to include a URL where the lightcurve plot can be viewed pending or following formal publication. This allows others to judge the quality of the solution for themselves.
