asn_from_list

Create an association using either the command line tool asn_from_list or through the Python API using romancal.associations.asn_from_list.asn_from_list()

Associations

Refer to TBD for a full description of associations.

To create an association, use the following command:

import romancal.associations.asn_from_list as asn_from_list
product_name = 'test_product'
items = {'r0000101001001001001_0001_wfi01_uncal.asdf': 'science', 'r0000101001001001001_3_0001_wfi01_uncal.asdf': 'guide_window', 'c': 'somethingelse'}
asn = asn_from_list.asn_from_list([(item, type_) for item, type_ in items.items()], product_name=product_name, with_exptype=True)
asn['asn_rule']
'DMS_ELPP_Base'

an example product that has both a science and guide window exposures would look like the following:

asn['products']
[   {   'members': [   {   'expname': 'r0000101001001001001_0001_wfi01_uncal.asdf',
                           'exptype': 'science'},
                       {   'expname': 'r0000101001001001001_3_0001_wfi01_uncal.asdf',
                           'exptype': 'guide_window'},
                       {'expname': 'c', 'exptype': 'somethingelse'}],
        'name': 'test_product'}]

To create a association with all the detectors for a given exposure from the command line,

asn_from_list -o detector_asn.json --product-name r0000101001001001001_0001_wfi data/*_cal.asdf

where the individual calibrated detector files are in a data subdirectory.

In addition you can also specify a target for the association file,

asn_from_list -o level3_mosaic_asn.json --product-name level3_mosaic --target 270p65x48y69 data/*_cal.asdf
