Attached st the bottom of this page you can find PSF images from the solar tower test.

Each zip file contains the following:

• a timestamped directory, identifying the acquisition. Inside the directory:
• an "irtc.fits" file, which is an IRTC cube (sequence of images), without any correction like dark subtractions.
• a timestamped FITS file, which is the dark for this sequence. This FITS file is usually a cube (sequence of images). In case an averaged file is present, this is used for the IRTC display and is not recommended for calculations because of rounding issues.

IRTC files have the standard header from IRTC software, plus additional keywords with information about the AO WFS state. Header uses the "HIERARCH" convention for long keywords.
