Data-The data shown in this paper can be found HERE.
Filter - Because the DLS does not have 4-pi acceptance, it is necessary to restrict theoretical calculations to the measurement phase space. The data analysis that produced the AA cross sections reported in this paper used acceptance criteria different from those used in previous DLS publications. Therefore, a filter unique to these data sets must be applied to model results. It is our intention to provide a complete and robust filter to the interested comunity which includes;
direct output of projected spectra (both model results and data)
access to the entire 3-dimensional DLS data sets.
Such a filter will exist in the coming weeks, to be released as DLS-Filter version 5.x. However, it has become clear that this final version of the filter will not be available as quickly as we intended. For this reason, we are releasing the simplified version of the filter which provides only the yes/no response to whether an input (Mass,pt,y) point falls within the DLS-AA acceptance. It does so without any smearing applied to the input variables. This acceptance filter is available here, Version 4.1 . It should work both on a UNIX SUN and a Digital Alpha VMS workstation.
The current version of the filter differs only slightly from version 4.0 which existed here previously. (To those who have used this previous version of the filter, the changes made in version 4.1 should have moderate effects on the model results, with slightly increased acceptances at large pairmass, and the explicit removal of cross sections below Mass=0.050 GeV/c2. ) The current version (4.1) found here can be used to make publishable comparisons with the AA cross sections reported in this paper. (A RMS mass smearing of 10% should be applied.)
Please report successes and problems to
us. If you download the code, please register with Howard
Matis, so you can be informed of
improvements to the code. The beta version does not have resolution
smearing included. If you want to compare a theoretical calculation
with our new data, this effect should be added.
