GN-2006A-Q-75-46-001 2006-04-08 12:16:18 PSF a bit diamond-shaped at low levels. Don't know if that's a problem. Since the science target has pixels above non-linearity in more than half of the images we cannot charge for those and therefore we also cannot charge for the PSF star.
GN-2006A-Q-75-46-006 2006-04-09 09:31:45 Upon looking at the PSF, we realize that the correction is quite poor, likely due to the cirrus which is reducing the rate we can guide at. Although the native seeing is within limits, at 100 Hz, we do not get a very good correction. Final few images show a double star. We do not know if the correction is poor or if the star is truly double. We will try the Hermione PSF to see if it shows the same behavior prior to going to Hermione. If it does, will abandon and go to specphots.
