how many images do u guys use for smooth turbulence profiles

hi,

how many images do u generally use to get a smooth turbulence profile like turbulence intensities, reynolds stress, etc.

i guess less images are okay for plotting a smooth mean velocity curve but smooth turbulence profile needs more images...

so how many images do u actually use, or how long do u record the flow?
