masking algorithm
Issue #6
resolved
- add <masks> block in xml parameter input
- allow different mask map for each observable at each frequency and Nside
- if not all outputs have mask, no mask is used in LoS integration
- if not all outputs have mask, a pre-check of mask and integration longitude/latitude limit should be performed while loading masks, to ensure the unmasked region is not ruled out by lon-lat limit
- if all outputs have mask, a global mask should be generated for minimal masking in LoS integration, and in this case, lon-lat limit should be inactivated.
- if all outputs have mask, a global mask generation should also consider the lowest Nside in integration and among all provided mask maps, dive to the highest Nside and generate the minimal masking map. (rule 6 is to ensure that no unmasked region for any observable is ruled out, converting low-res mask to high-res mask is fine, while converting high-res mask to low-res mask through HEALPix function does not satisfy out minimal masking principle)
