Does the Risoe TL/OSL reader system display TL inherently as (TL/heating rate or channel) leading to misinterpretation of heating rate effect on TL?

Even for equal doses when effect of heating rate for given TL glow curve on different identical samples of same TL material, the results on the effect of heating rate on TL glow curves lead to...
