Hb. Larsen et G. Thorkildsen, Comments on Extinction-corrected mean thickness and integral width used inthe program UMWEG98 by Rossmanith (2000), J APPL CRYS, 33, 2000, pp. 1447-1447
Comments are made on a paper by E. Rossmanith [J. Appl. Cryst. (2000), 33,
330-333] concerning the use of asymptotic expressions for the extinction-co
rrected mean thickness.
