It seems this PR removed the ASF header in omni and orionbelt converters. It's a requirement to have the ASF header, so we should keep it.

Thanks for the review @QMalcolm @khush-bhatia @jbonofre . I had addressed the last reported issue with missing ASF header. The missing ASF header had been restored now.
