Hi Eric,
This is the 7-year data. The previous one was data taken after 5
years. I used puth and it works now. Thanks.
Should I be worried if I use a few degrees of the galactic center for
comparison with other images?
What should I tell the person who is charge of WMAP data?
Your advice will be appreciated.
