Hi, nice idea to include a cut-off feature in the new version. Just wondering:
- if it's applied, will it cut off all inputs at the specified level throughout the product system when the software assembles that using the auto-complete option?
- is it insensitive to the unit in which flows are specified? So if I specify a cut-off of 0.001, any input flow whose value is <0.001 will be cut off, whether it's 0.001 tonnes, items, MJ, etc.
Thanks for clarification!
PS, nice new graphic device ;-)
Cut-off feature in v1.4.2

Hi Chris,
thanks -

yes, exactly.will it cut off all inputs at the specified level throughout the product system when the software assembles that using the auto-complete option?
units are converted to the reference unit (so e.g. g, kg, t will be converted to kg); different unit groups will not be converted "to each other", so e.g. volume and energy and mass units will be considered in their respective reference units.is it insensitive to the unit in which flows are specified
Best wishes,
Andreas

Thanks Andreas,
One further query: is the cut off instruction sensitive to the sign (positive/negative) or just to the absolute values of input flows?
So, for example, if cut-off level 0.001 is specified, will all negative inputs (i.e. all wastes, in current ecoinvent convention) be cut off as well as positive inputs at or below the threshold? If it is sensitive to sign that would seem to make it a lopsided instruction. In that case could it be changed so that it runs from the absolute value instead?

Chris

Hi Chris,
indeed, good point, the threshold always considers the absolute value, irrespective of the sign.
