PNe20 - How many PNe need to be
observed to see a trend
in the data?
This is an important question and is easy to determine if the number of
PNe observed by Feldmeier and Aguerri are adequate to see the signal
from their correlation to light.
FOR NOW: Only 3.fits/3m.fits have been completed [or are being
completed] for this version - it takes a while
Now, we've adjusted the size of the catalog subsampled from the
original theoretical list. We are trying the following catalog sizes:
All in terms of % of observed numbers with # PNe in the catalog below
them:
[for 3.fits/3m.fits]
10%, 50%, 100%,
200%, 300%, 500%
7 , 37 , 75 , 150
, 225 , 375
[note: for 100%, the results from PNe16
page were used]
We will again repeat this for various contamination fractions:
0%, 20%, 40%, 60%, 80%, 100%
And it will be performed on all of the fields, masked and unmasked,
over the usual set of half-box widths, in pixels:
1, 3, 5, 7, 9, 11, 13, 15, 25, 35, 45, 55, 65
