well i just finished a good bit of editing i haven't had a chance to go through and do all the tagging and referencing yet since work calls but i am extremely confident in the scientific factual basis of everything stated in here the referencing can pretty much be all made to the book particle imaging velocimetry a practical guide by raffel willert wereley and kompenhans if someone can add it also not sure how to exactly do that as it all can be found in numerous scientific journals databases etc but is so conveniently placed all in that one book the only thing i am unsure about as i have no experience with is molecular tagging velocimetry to put it simply i would like to keep technique defects in the summaries but i don't know what this one's is to put is bluntly the description as it is now is too good to be true i know it has defects and problems i don't know what they are the fact is the technique was developed in ish and is not in widespread use if the description were accurate everyone would use it i have met or heard of not one person using it which means there is some big flaw in the technique that if someone can find be my guest to add it everything else please post on discussion page before editing critical information as i am positive what i have said can be completely defended but am open to solid arguments i won't be pigheaded about it also anyone with knowledge of tomographic piv please expand the section it is a volumetric analysis technique that i know of and know its new but know nothing about
