Can't find [Flat] files? #4

Closed sirpercival closed 9 years ago

sirpercival commented 9 years ago

I'm not sure I understand how the tag system works. I'm trying to use the isaac_spc_flats recipe to create a master flat file. I've tested that my ElementTree + XPath parsing works as it's supposed to; when I then call the recipe with master_sp_flat = isaac_spc_flat({'raw':flats}), I get [ ERROR] Cannot find flat frames in the input list.

Is there some other way that the recipe is supposed to know what the flats are? Or am I missing something? Thanks!

I am not sure about isaac: what is the input tag needed here? I would guess that the input tag is "flat", and not "raw", so you could try

master_sp_flat = isaac_spc_flat({'flat':flats})

I really don't know... this is the problem I'm running into. Changing raw to flat (and sp_flat, I tried that too) led to the same error. The particular recipe is in this pdf ftp://ftp.eso.org/pub/dfs/pipelines/isaac/isaac-pipeline-manual-1.4.pdf on page 48.

Try 'SP_FLAT' (capital letters), as stated in the manual.

Aha! That's it, and I now understand :) Thank you!
