Re: PEC Curve Analysis

Stephen Winston

Hi Jerry,

One quick comment on your data:  Your imaging pixel scale (6.3 arc-s pixel) is almost as big as the measured pk-pk PE (5.3 arc-seconds).  Or in other words, the PE was measured over less that 2 pixels.

What imaging train were you using to measure your PE?  If possible yo might want to use a longer focal length  instrument or different camera (smaller pixels) as it will probably give a more accurate measurement.

And to be clear:  I'm not saying your measurements are not accurate, but at that imaging scale it's hard to tell.
