Submitted Lightcurve Parameters  (Search page)
The Search page shows summary information for lightcurve parameters submitted to CALL.

 

If you use the information from this page, please give credit to the original author(s) and, if necessary, obtain permission from them. You should also note that unless you obtain the data otherwise, it was retrieved from the listing on this site.

 

In all but a few cases, the results in CALL appear in the asteroid lightcurve database (LCDB) and usually with a reference to the person's web site or journal where the results were eventually published. The CALL site is not meant to be the final resting place for your work.

 

Submitting Data to ALCDEF

The Asteroid Lightcurve Data Exchange Format (ALCDEF) was introduced at the 2010 Division of Planetary Sciences meeting. The idea is to standardize  minimum data requirements and format so that exchanging data sets among researchers is as simple as possible.


The ALCDEF initiative also includes storing data on a long-term, centralized system that will be regularly maintained.

 

The Minor Planet Center has taken on that task, which includes uploading and downloading data. As the MPC site develops, it will be possible to download selected subsets of data for a given asteroid (in ALCDEF compliant format) and even view plots of the raw data for a given lightcurve.


It is vital that asteroid photometry be recorded for posterity

Lightcurve data can be used to determine rotation periods and model the spin axis and/or shape of an asteroid. Far too much of past data are in disarray, following any number of formats, if available at all.

 

Please consider submitting your data to the ALCDEF database as soon as possible.
