PROFFIT: Analysis of X-ray surface-brightness profiles

Abstract: PROFFIT analyzes X-ray surface-brightness profiles for data from any X-ray instrument. It can extract surface-brightness profiles in circular or elliptical annuli, using constant or logarithmic bin size, from the image centroid, the surface-brightness peak, or any user-given center, and provides surface-brightness profiles in any circular or elliptical sectors. It offers background map support to extract background profiles, can excise areas using SAO DS9-compatible (ascl:0003.002) region files to exclude point sources, provides fitting with a number of built-in models, including the popular beta model, double beta, cusp beta, power law, and projected broken power law, uses chi-squared or C statistic, and can fit on the surface-brightness or counts data. It has a command-line interface similar to HEASOFT’s XSPEC (ascl:9910.005) package, provides interactive help with a description of all the commands, and results can be saved in FITS, ROOT or TXT format.

Hi Dominique,
I encounter the error code while installing PROFFIT. The error message is :
/usr/local/include/root/RStringView.h:19:10: fatal error: 'string_view' file not found
#include <string_view>
1 error generated.
make[3]: *** [CMakeFiles/proffit.dir/proffit.cpp.o] Error 1
make[2]: *** [CMakeFiles/proffit.dir/all] Error 2
make[1]: *** [all] Error 2
make: *** [all] Error 2
Do you have any idea what goes wrong? (I have installed cmake and ROOT following this webpage : )
