Methods Documentation

process(input)

This is where real work happens. Every Step subclass has to override this method. The default behaviour is to raise a NotImplementedError exception.

process_exposure_product(exp_product, pool_name=' ', asn_file=' ')

Process an exposure found in the association product

Parameters:

• exp_product (dict) – A Level2b association product.
• pool_name (str) – The pool file name. Used for recording purposes only.
• asn_file (str) – The name of the association file. Used for recording purposes only.
