In all measurements with the usage of proportional counters the pulse height and its distribution are measured. From this one can calculate energy losses and their distribution along the particle track position in 2D. The pulse height at the output of electronic circuit, co-working with the proportional counters, depends on: gas gain, energy deposited inside a counter and parameters of the readout electronics. However, it is only the first approximation. Careful studies show that output pulse height depends on the place of radiation absorption along and across the counter. The measured effect is as high as a few percent across and along the counter. Those effects were observed for both cylindrical and rectangular geometry. The pulse height depends not only on the registered count rate but also on the speed of its change. All the above effects are a few percentage effects, but can strongly affect the correctness of measurement made with the usage of proportional counters.
