CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999Subject: CHOOCH problem From: Truc Kim curtmik {- at -} GMAIL {- dot -} COM Date: 2007-07-06 Hello everyone, I used CHOOCH program to find f' and f" value for bromide. My input file was modified that the 1st column is the energy and 2nd column is X-ray flux. Could you tell me the problem when I got the following information: Spectrum over br K edge at theoretical energy of 13474.00 eV Warning: Insufficient data - assuming constant value of 3.621363 in normalisation gsl: qag.c:261: ERROR: could not integrate function Default GSL error handler invoked. Abort Thank you very much, CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999 |
