Hi,

MARS DR1 release date is being very close now, so this is the moment to officially publish the coverage maps of the first data set.

The following maps show the northern and southern hemispheres with the superimposed image rectangles. The grey level in each pixel of the maps corresponds to total exposure time, the white being 50 hours.

Coverage is not uniform. Homogeneity will be better after two years of observation. But, right now, it is a huge amount of data. Most areas being covered have total exposure times between 10 to 40 hours. The new MultiscaleGradientCorrection tool will always use the maximum data available in the image database according to the field you want to correct.

We are now considering including the [O-III] data in DR1. In my opinion, this band will probably be included in the Extended Data Release 1.


Best regards,
Vicent.
 
If the filename is of any consideration (MARS-DR1-1.0.3), then it should be already DR3.

Cheers
Tom

The northern hemisphere broadband and Hα maps have Octans, a circumpolar southern constellation ( or at least its label) situated between Delphinus and Equuleus

I would exspect a DR3 to be called something like "MARS-DR3-X.Y.Z".
However, i dont know if there was a MARS-DR1-1.0.0, and if included a smaller coverage of the sky or not.

So maybe I am stupid, but can someone tell be which MARS files I need to download, and where do I put them, as I see 2 files on the PI website..?
 
Ok thanks, so the files are currently in my download folder, so if I add them in the MARS window, and then delete them from the download folder, then I will have lost them as they are not actually stored in PI, so back to my question, is there somewhere beat to put them within the PI folders ??

You have to put them somewhere on your drive, same as with GAIA files.
If you remove them then of course you won't be able to use them.

Anywhere other than the PI folders themselves as those are deleted during a version upgrade. I have a folder called 'PI Database Files' that contains MARS and the GAIA databases.
 
I just recently discovered that my camera (KAF 16200A sensor) and one of my scopes (645 mm) provides a FoV or just a tad over 3. I am in the southern hemisphere. Most of my targets don't have a MGC information so I thought why not upload NB masters. Almost none of my stuff has been drizzled so to provide it, I have to run it all though PI again which takes time. Is there some method of checking whether the data has already been uploaded so I don't waste time and effort in re processing the targets again?

I think the PI team would be very grateful for your SH NB data. The more data in MARS the more valuable it will be and even if the areas covered by your files exist, the coverage will be different and as MGC stacks reference frames, the quality of the stacked reference will be higher.

Did you get an answer for your question? I have some targets using the Optolong L-eXtreme filter but I can't find any indication of whether or not they are wanted.

you can always upload the files following the info listed here:

Thread 'Dedicated MARS Website Section / MARS Data Upload System'

Hi all,

I am glad to announce that we have just released a new section of our corporate website dedicated to the MARS project:

The Multiscale All-Sky Reference Survey (MARS)

In this page we provide general information on MARS and a list of relevant resources. We have also completed the development of a web-based front-end system for uploading user-contributed images:

MARS Data Upload System

User-contributed data will be uploaded directly to our corporate server in Virginia, USA. Our working servers will download and analyze the images, which will be...

I've made an image of Bode's Galaxy and was excited to use MARS on it since I have massive gradients, well it seems like that area isn't covered.
Are there any plans to release more "data" anytime soon?

Hey there! Is there a way to get these maps onto stellarium maps, so i can check framing for MGC before shooting, or how much i need to crop an existing dataset for the area to be covered? that would be super useful thanks :)
