StarGenerator rounding error?
« on: 2010 January 15 15:32:22 »
I think that I have found a problem in StarGenerator. The stars seem to be ordered in a grid. For example, in the attached screen capture there are lots of stars in the same horizontal lines. Is there some rounding error in the generated star coordinates?

Hi Andres,

Thanks for reporting. Take a look at this screenshot:

So, what's happening here?  ::)

I'm starting to think there is something really wrong with the Windows version of StarGenerator, as the Linux and Mac OS X versions seem to work flawlessly. I'll check it out tomorrow.

Hi Juan,

I can't see your screenshot: "Firefox can't find the server at pteam.pixinsight.com."

Anyway, I can confirm you that I am using the 01.05.09.0561 (x86_64) version in Win7. The version of the StarGenerator module is 01.00.05.0047.

Andres,

Please try again. It must have been a brief server downtime. Now the link works.

I have tried to align one of my images with your image and the result is quite good: 0.5 pixels RMS. Trying it with the image generated with the Windows StarGenerator module does not find a match.
