What's new and what's to be expected?

What's new
A brief list of some 'major' events during the last 10 years. By no means complete.
- July 2023
- On the surface it seems that NN-OnLine has been rather dormant last 2 decades. But out of sight it's still maintained. Technically and content-wise. Next year we will celebrate our 30th year of existence. You will notice :-)
- March 2005
- A new server has been purchased.
Despite a huge lack of time and financial resources a 'new' server has been bought off eBay to replace the current one. Another HP PA-RISC machine, model C3000. Somewhat faster and somewhat more memory than the current server. Expected time to be used will be summer 2005. - June 2004
- NN-OnLine had moved to its own domain: http://nn-online.org
NN-OnLine has been 'restyled'; pages are now generated with PHP and stylesheets are used to suggest a preferred presentation to the browser. - February 2004
- A new program has been added that allows you to compare your own experimental data with theoretical models.
- January 2004
- A `new' server has been bought for NN-OnLine. It's a HP again, a model C200. It's only half the age of the old server that is over 12 years old. Together with the planned revamp of the site (that is very necessary) it is a nice part in NN-OnLine's 10th birthday celebration this year.
- June 2003
- On request a new program has been added to make `abundandeplots' of the NN database. The output is still somewhat primitive, and the current implementation of that database lacks flexibility to do refined searching. Yet is still may be useful.
- October 1999
- The ESC96 potential is added.
- July 1999
- A separate page is made listing all the computercode that is available. Hopefully this list will grow in the future.
- March 1999
- After a break of more then 20 years new low energy YN scattering data have been become available!
- July 1998
- The 3d surfaces for observables are now also available in VRML
- June 1998
- You can submit your own experimental data and calculate the chi**2 w.r.t. some models
- June 1998
- 3d surface plots of scattering amplitudes or observables versus energy and angle can be made
- December 1997
- For all eprints a PDF version is available
- August 1997
- NN-OnLine completely refurbished - new interactive programs (the NN database, NN scattering amplitudes)
- May 1997
- The database of hyperon-nucleon scattering data is available
- January 1996
- NN-OnLine is an independent server with its own address: http://nn-online.sci.kun.nl
- August 1994
- NN-OnLine is born
What's to be expected
Plenty of ideas and plans, but as NN-OnLine is a one-man operation and not funded ... it may take a while sometimes before actual realization takes place.
- Ten years after PWA93 the newest χPWA03 has been finished. Preliminary results have already been published, later in 2004 the final results are expected to be published.

NN-OnLine's 10th birthday is coming .....
As NN-OnLine is approaching it's 10th birthday, progress is made to update the somewhat outdated user interface. Of course minor improvments are continuously made! - A full-featured hyperon-nucleon (YN) section is expected to be finished end of 2004.
- An improved interface to the database. It is our aim to make the database completely documented (like a digital mixture of the Data tables of Bystrický and Lehar and the NNDC database) with all relevant information needed to treat the data correctly in a data analysis.
- Even more information on the pion-nucleon coupling constants.
- More and better information on the properties of the deuteron and low-energy parameters, e.g. effective ranges and scattering lengths.
- Extending the list of publications by going back in history to the 60s. As the list is growing longer in time anyway, a friendlier interface to a database backend is being made.
- General improvements in the user interfaces. CSS stylesheets have turned out to be useful already, yet we are currently looking whether deploying some javascript or XUL applications may enhance the NN-OnLine experience.
- Adding a useful list of various external links.
- .... any useful suggestions YOU have?
