Hi Valeri,
Based on my >20 years of experience in HEP I share your viewpoint that a FITS format for standard accelerator HEP experiments is not a very useful/efficient way of storing the data (unless one only has calorimeter like data).
Furthermore, I am not stressing the need for the FITS image data (although it would be nice to support that too), but my first interest goes for the physics data blocks of the FITS structure so that I can analyse satellite (e.g. Batse, Swift) and EAS data (like Veritas, HESS) together with our IceCube data which are already in ROOT.

So, in case you have something which needs to be tested, just let me know so that I can be the guinnee pig (as usual :), since we have quite a bit of data available.

Cheers,
Nick.

Hi,
thanks to everybody who answered to the "FITS and ROOT" thread. Actually intention to support of FITS image (say picture) format in ROOT was declared at the first introduction of TImage/TASImage class (kFits file type from TImage.h) but was not implemented. We will revisit it soon.
In connection with previous topic "wikipedia & ROOT", I was slightly surprised by mention by Andy the FITS format (which is in general a table of numbers) as format for saving of HEP data, which is in general has hierachical structure.

Thanks.
Regards. Valeriy

Hi Nicolas,
Yep, I have also mentioned to Valeri (cc. to Rene and Fons) that a native FITS in ROOT would be great w.r.t. the multi-messenger campaign we are currently setting up between the IceCube and the gamma ray community to investigate astrophysical objects both in EM radiation as well as in neutrinos.

Cheers,
Nick.
