latest xspec patches

12.4.0ak The cutoffpl model can show a distortion for very low energies (E/B approx. less than 10^-3). The incomplete gamma function calculation which this is based on needs to be improved in this region. Our thanks to Joern Wilms, Moritz Boeck, and Manfred Hanke for pointing this out. Report added on Aug 28, 2008.

12.4.0al This adds the Fortran wrapper function xgtcht(console,log) for those wishing to retrieve XSPEC's console and log chatter level settings from inside their own Fortran local models. The function is equivalent to the xgtcht contained in the xanlib library used by XSPEC11. Report added on Aug 28, 2008.

12.4.0am Enhancement patch required for reading data sets and responses in the new format used by GLAST GBM files. The modifications include the removal of the SPEC_NUM column for type-II data files, and the storing of multiple response matrix extensions into one response file. XSPEC will now distinguish among multiple response extensions by appending a curly-bracket specifier to the response file name: myResponse.rsp{n} where n is the EXTVER keyword value of the extension. Report added on Aug 28, 2008.
