S2SRO products - new re-reduction

The S2SRO products have been regenerated once again. In this batch you will find

  • Much improved map for extended emission targets (which now are specially handled)
  • Improved step-finder
  • S/N masking for bright sources to prevent negative bowling
  • Point source observations now reduced with the science recipe rather than the summit "quickie" recipe.

As usual you will find your SCUBA-2 products in the proprietary processed data search - just put in your project code and choose multi-night to get your total product. 

(Note that this  batch does not include the map-based despiking - that will be in the next run).

hi,

we've been looking at the multi-night data for NGC 1333 - why would several overlapping images have different group files rather than one combined mosaic? The data were taken in 12/09, 02/10 and 03/10 so maybe things changed with SCUBA-2? Is one dataset the best one?

thanks!

I have not looked at the data yet, but I am guessing the data had different base positions?

You can put them all together with WCSMOSAIC.

We are working on a fixed-tile co-adding process that will give you all data taken in a pre-calculated tile as one image.
