HST WCS Headers

[Philip Bergen]

Aloha,

Is there a way to configure AM.net to generate HSTWCS headers for use with astrodrizzle?

Thanks,

Do you mean to recognize HST images?  Out-of-the-box, no.  The ACS camera (biggest field of view) is only about 3 arcmin square, so no all-sky astrometric reference catalog has enough stars+galaxies to recognize them blindly.  It is possible to build a custom index to solve them using deeper overlapping imaging, but that is a step up in difficulty...

cheers,

Hi Dustin,

No I want to use my own images but the drizzle libraries to put them together.

I have never used drizzle but maybe someone else has managed to convince it to work.  From what I understand, the new "AstroDrizzle", (previously called "BetaDrizzle", and maybe now just called "Drizzle") is generally more sensible and less HST-specific.
