Hello,

I have been working my way through the AstroImageJ expanded paper and had a question about how the fixed values of u1 and u2 are extracted. The paper states that they are extracted from Claret & Bloemen (2011) using the website tool http://astroutils.astronomy.ohio-state.edu/exofast/limbdark.shtml. I was wondering how, exactly, those values are extracted-- specifically, does the program use the website tool as it is processing the data? Does it utilize the "select planet" option, even if the planet being observed is not one of the planets included in the database?

Thanks for your clarification!
