In Innsbruck

So! Trip to Innsbruck was good and calm, no problems with the trains.

Took my time in the trip to prepare the ACS images (bringing them back to counts, instead of counts/sec and putting the original sky back) and to get more information about weak lensing.

Gave my talk today and people seemed to have liked it. There was some nice questions, for example about how much of the galaxy light is absorbed by dust and how this would influence the IGL fractions. Infrared data could tell us that.

Got a nice reply from John Krist, one of the authors of Tiny Tim, telling me that TT doesn't take the transformations from MultiDrizzle in consideration for ACS PSFs. So that the option in the case would be generating the models for the "wished" positions, put it on a raw image and drizzle it and get the drizzled model back. Talking to Marco Barden, he said that better than using TT PSF is to get a considerable number of stars from the images and generating a good, high-S/N PSF (as they have done for GEMS). So that will be my approach on this case.

Tomorrow we'll start with the GALAPAGOS and some discussions about simulations!!
