Aspect L1 products

The mica.archive.asp_l1 module provides tools to build and fetch from a file archive of Aspect level 1 products.

Methods are provided to find the archive directory:

>>> from mica.archive import asp_l1
>>> asp_l1.get_dir(2121)
'/data/aca/archive/asp1/02/02121'
>>> obsdirs = asp_l1.get_obs_dirs(6000)

The obsdirs dictionary should look something like:

{'default': '/data/aca/archive/asp1/06/06000',
2: '/data/aca/archive/asp1/06/06000_v02',
3: '/data/aca/archive/asp1/06/06000_v03',
'last': '/data/aca/archive/asp1/06/06000',
'revisions': [2, 3]}

Methods are also provided to retrieve a list files by obsid and time range.

>>> obs_files = asp_l1.get_files(6000)
>>> obs_gspr = asp_l1.get_files(6000, content=['GSPROPS'])
>>> range_fidpr = asp_l1.get_files(start='2012:001',
...                                stop='2012:030',
...                                content=['FIDPROPS'])
