Michael and Dave G,

I actually have over a 1,000 images of galaxies taken down to about 19.5 mag. It's been awhile now since checking them. I sent a certain amount of them to Dave Mc about a year ago for the north polar region he was interested in targeting. The pole region is a fertile area as most supernova hunting is been carried out in lower latitudes.

They could be sent as a CD to the blinkers or easier still, I could send them the target ones for the region we are interested in. If I recall they were not in FITS format and I think I forgot to provide the coordinates only NGC numbers. I'll have to check this all out.

May be Dave Mc could refresh my memory regarding the above.

Sorry for the tardy reply folks...

Thanks to the additional volunteers - I've added your names to the list. So far, we have 5 imagers and 11 blinkers.

There is some work taking place on blinking software so we'll see how that pans out. There is also at least one other option. I think it is important, as pointed out, that blinking should be available to all, regardless of their platform. So that's what we will try to ensure.

As regards the database of target galaxies, I'd forgotten that you had the 1000+ images Eamonn :oops:

For the target list to work, we would need RA/DEC co-ordinates. An NGC name could give us that though (with a bit of detective work). We might also need to filter them for anyone using a fork mount - given they are concentrated on the NCP region.

They will also need to be in FITS format. And that raises another point - imagers should produce images in FITS format also. Can I assume you can?

I'll work on a process flow over the weekend to determine how this thing will work. We can then start to get the tools together that will facilitate the process.

This said, I would really like to get some images off to the blinkers so they can try things out. I personally have a number of galaxy images that can be used for a blinker trial. Does anyone else? Eamonn?

Cheers
Dave

Hi Dave,

I'm afraid I won't be able to volunteer for any blinking imaging :lol: but I noticed your comment about going by the NGC number.

The NGC/IC project at www.ngcic.org/ has done a trojan job of cleaning up the errors in the catalogue and is a good reference now.

An even more amazing achievement is Steve Gottlieb's observations of ALL the NGC objects -- the full list of his observing notes is at www.ngcic.org/gottlieb/default.htm :!: :!: :!:

atb,

John

John - they're superb references! Thanks for posting them on.

Very interesting to see Birr played a part.

Cheers
Dave

dave you add me in for some blinking, maybe in the future for some imaging.

Unofficial Answer: What the I.T. doesn't know won't hurt us:). Except if you have to install software. The audit software would pick that up.


And on the offchance that the software will run on Solaris and that it is completely automated I can borrow a lot of cpu cycles at work :-)

There must be some software that can automatically do the blinking? It needs to align the images, match the brightness & contrast then flag anything thats different over a certain threshold. A tedious manual process.

Cool!

There must be - but I wouldn't have a notion of where to look. I think that if it out there, its probably proprietary. Still, if anyone comes across such a beast, that would be super. Of course, if anyone one to write such a beast...

Have you seen this guy's stuff Dave?

www.supernovae.be/supernova.htm

I don't know if it is available to download anywhere however or if he would be agreeable to share with the AOP?

Also, I think there might be some software tucked away somewhere from the team that ran JANet and StarLink which were the UK observatories network. The systems team was disbanded due to funding problems (a terrible decision in my mind) but the members still have pretty amazing software on a site whose name currently eludes me. I should have a reference at home. It might have stuff to do blinking -- certainly they wrote a lot of image processing software -- but I am not sure if it's what is required for this programme.

atb,

John

That is very interesting John. I've sent an email asking if there is anything he could offer. Its a very well thought out package and it looks very good.

I had a look for JANet and StarLink - I found a couple of good sites. But to be honest, it looks pretty complicated. I'm working through the SExtractor manual to see if it will do the trick. I got another link to ESO - they have a distributed CD with all kinds of software on. But again, I think its pretty complex professional type stuff.

Thanks for the info - its certainly opened up a few more paths.

John L - you're on the list!

Dave Mc,

I'll send you on the IC, MGC and NGC list of around 1,000 galaxies.
I've only got images in jpeg. no FITS images

Michael, they are only listed by the above catalogue numbers, ie. no coordinates or mags. Each galaxy is raw and stretched images.

That's ok Eamonn. Once we have a list we can get the magnitudes then.
