[Aavso-photometry] Cosmic Rays

[Ben Davies]

If a cosmic ist falling into the sky annulus, is often not too serious 
asmost (advanced) photometry packages have implemented some kind of 
outlier rejection.

Hi Woolfgang,

I believe that you are right about this in most cases.  However, a 6 x 
42 pixel cosmic ray is not uncommon and this will fit nicely into 
annulus rings set at 15 and 24.  That is 25% of the pixels being 
changed.  Here, there is surely there is some scenario of pixel values 
that will screw up any ourlier rejection scheme.

But I guess I would say, if you don't have to take a chance, why would you?

Thanks for pointing out the usefulness of the method in detecting 
asteroids.  I believe it will find anything in the images that varies in 
time or in space.  And thanks for pointing out last week the links to 
the studies on cosmic rays.  I don't know how you always come up with 
these things.  You either have one great database of links, or you have 
a gift for choosing the right search terms.
