Andromeda Mosaic

Darius,

No worries, I just got back from Japan and busy myself catching up on everything at home.

 

I am missing the following datasets:

2113
2114

The only complete channel I have is the Luminance channel.

Daniel

Okay, all right.

I will upload the two datasets tomorrow.

Once the upload is complete, I'll get back to you via private message.

These are the channels with the missing panels.

Looks like I am missing the following sets:

2113
2114
2114 Ha
2117
2118

Some of these dropped off right after my pier 3 membership started.

Hello Daniel,
Sorry for the late reply. I had a lot to do in the last days. These are all the datasets for the M31 mosaic that I have. Which ones are you missing?

PS: I just submitted an additional job, because the position of the additional data for panel 4 does not match the original data.

And I have downloaded the subs Dark Astro shared through dropbox.

Some one I am still missing one panel in each color channel. Maybe I discarded too many bad subs. Just to verify are all the panels available?

Luminance is looking pretty good. There is one different panel missing from each of the RGB_Ha channels.

Daniel

Do we still M31 submissions 2213, 2214, and 2217?

Daniel

Hi everyone

The requests for the M31 project have been uploaded (only got 2 of the 4 wrong first time).

CS, Earle

Hi Darius, 

That's fantastic and thank you for the effort you have put in on this. Between yourself and Earle I think you've come up with the best solution. Looking forward to this.

Cheers and CS,

Hello all,
I have uploaded all datasets from the M31 Mosaic.

Panel 1: https://www.dropbox.com/s/vic9jws4f1ktysp/1754%20p3%20m31%201%20833.zip?dl=0

Panel 1 (red channel): https://www.dropbox.com/s/nzc4kcoo83qgmiy/1898%20p3%20m31%201%20red%20833.zip?dl=0

Panel 2: https://www.dropbox.com/s/febsxppmuhyjzyv/1755%20p3%20m31%202%20833.zip?dl=0

Panel 3: https://www.dropbox.com/s/cj6gztp99bfoj8z/1756%20p3%20m31%203%20833.zip?dl=0

Panel 4: https://www.dropbox.com/s/8cy0tudni81hjl2/1757%20p3%20m31%204%20833.zip?dl=0

I have already sorted out the bad subs. Panel 3 had a lot of bad subs in it. Some of them I wasn't sure if you can still use them. You'll have to look through them yourself and decide which ones you want to use.

I would include the following additional data for the Mosaic:

Panel 1: 30x180s Ha
Panel 2: 30x60s Blue, 60x60s red, 30x180 Ha
Panel 3: 60x60s Red, Green, Blue, 30x180s Ha
Panel 4: 60x60s Blue and Green, 30x180s Ha

What is your opinion?

CS

Darius

Hi Earle,

30x180s for Ha sounds good to me. I am in the process of uploading the old datasets. As you mentioned, the red channel for panel 3 is bad. I left it in the dataset anyway because I am unsure if you can use it. Nevertheless, I think we should retake the red channel for Panel 3.

CS

Darius

Hi Darius,

Of course the coordinates are there; I hadn't thought of that. I've gone through plates 2,3 and 4 to check the quality; The green and red on plate 3 are poor and there are some missing sets.

What do you think about Ha exposures? The RGB are 60x60s; would 30x180s sound reasonable?

CS, Earle

Hi Earle,

you can see the coordinates in the syndicate submissions list. I already have the coordinates figured out and will attach them as a screenshot to this reply. I will upload the old datasets in the course of next week. To save space on the cloud storage, I will check all datasets before uploading and sort out the bad subs and upload only the good ones. Once all datasets are uploaded, I will provide the links in this chat.

CS

Darius

Hi Daraius,

I see that Ray gave a thumbs up to the suggestion of completing the four panel Andromeda with Ha. Why don't we just do that.

Do you wan to upload the requests? I can but need the coordinates for pane 1.

By thee way, have you checked the existing data to see if any needs repeating? I didn't becaus I only had partial data.

CS, Earle

Hi Earle,

I would post the links in this chat. Then all members should see it. Maybe the Roboscopes team would be kind enough to upload the files to their server:)

CS

Darius

Hi Darius,

I'm certainly happy to go with this.

I'm not familiar with the way that we can communicate within the consortium. Is there a way to bounce the idea past the others? (Do we even know who is in the consortium?)

Kind regards, Earle

Hi Earle,

I really like your suggestion to finish the 2x2 mosaic and add Ha. I have all the old datasets from the mosaic. I can make them available on a cloud storage in case some members do not have the data.

Hi Darius

I am of two minds here. Probably many of us have M31 images taken with wider field scopes.

What makes the 3x3 project attractive is the resolution of the system (0.7 "/px at 1x1 binning) The 3x3 gives better coverage of the galaxy. I guess your 2.5 h/panel is 30 m RGB and 60 L, which will work if the subs are good.

We could simply add what is missing  from the previous project. From what I have, 1755 (Panel 2) has LRGB, 1756  LRG and 1757 LR, so only three sets are missing, 2xB and 1xG. I don't have 1754. If we can share these with other members (?) we could finish the earlier project.

A suggestion would be to complete the earlier 2x2 project but add Ha to bring out the star forming regions. Given what is already done, this might be the most effective option.

Thoughts?

Anyone else have inputs?

CS, Earle
