Greetings A@H Team!

I have a few questions.

1. What lightcurves do you use? Do you use ALCDEF from MPC site?
2. Do you really work with photometric data from big surveys?
3. How and where I can post my LC for your project? It will be useful or not?


TIA,

Now we use sparse-in-time photometry from astrometric surveys. For lightcurve inversion, we also use lightcurves from ALCDEF/MPC but they are processed at the computational cluster Tiger of the Astronomical Institute, Charles University in Prague, because their analysis is not so time-consuming.

2. Do you really work with photometric data from big surveys?

Yes, we do.

3. How and where I can post my LC for your project? It will be useful or not?

Post your lightcurves at ALCDEF/MPC. Sooner or later we will download them, combine them with other available data, and try to derive a model. If we succeed, the model will be posted on DAMIT http://astro.troja.mff.cuni.cz/projects/asteroids3D.

Yes, we do.


Do you use photometric data from all observers who send measurements to MPC?

We don't use all data from MPC, just a subset - outliers were removed and the data re-calibrated by Edward Bowell from Lowell Observatory.
