How to get co-registered cutouts of multiple image surveys as color image
-
NOTE: This compute job requires you to register at the NVO login site.
-
First go to the NVO compute services site at http://www.us-vo.org/oldhome/nesssi/
-
Click on "Click here to try Nesssi" (1)
-
If you do not have a login (2) then register at the NVO login service. You will need a valid email address, a confirmation token will be sent there, and you use it to complete the process.
-
You will get directed to the Nesssi services page with the paleolithic burial chamber top-left, and your username should be displayed (3).
-
Now click on the DPOSS mosaic service (4).
-
Fill in the sky position of the center, and the width in degrees that you would like (5). The resolution will be one arc-second per pixel. It will take a few minutes to reproject and mosaic an area half a degree on a side.
-
Click "Submit" (6) and watch for a red flag that says "Loading" at the top right of the window.
-
You can then click "Monitor" to see the progress of the job. There is a URL that shows the files being accumulated in a special sandbox area for the job (7), click on that to see what has been made. There is also a queue status line (8) which shows that the job is running by the "R" at the end of the line.
-
Finally, a file will appear in the sandbox called "mosaic.fits" (9). In this case it is 169 megabytes. You can download it from the URL.
