Initial results of "better" ORAC-DR reduction

As previously mentioned, ORAC-DR is improving how ACSIS data are reduced. To show the progress between "summit" and "better":

• integrated intensity map, group coadd: summit better


• integrated intensity map, single observation: summit better


• intensity-weighted velocity map, group coadd: summit better

A few notes:

• By "summit" pipeline I mean the pipeline currently running at the summit. This pipeline will be replaced by an "improved" pipeline pending JCMT support scientist approval. The "improved" pipeline will not be run at CADC, they will run the "better" pipeline that created the "better" images linked above.


• The "group" summit integrated intensity map is not generated by the pipeline, it's created by manually running wcsmosaic to mosaic together the individual baselined cubes (the _reduced CADC products), then collapsing over the entire frequency range. This is how the summit pipeline would create those files, though.


• Ditto for the group summit velocity map, except the pipeline wouldn't even create those in the first place, as it doesn't know which velocity ranges to collapse over to get a proper velocity map. This example is just done by naively collapsing over the entire velocity range. The "better" pipeline automatically finds these regions and creates velocity maps -- not only for the coadded group cube, but also for individual observation cubes.


• The difference between the "better" pipeline (which is what will be running at CADC) and the "improved" pipeline (which is what will be running at the summit) is very small for this given dataset.
