 <p>If you select the source table orange box, Rabbit-In-a-Hat will expose values the source data has for that table. This is meant to help in the process in understanding the source data and what logic may be required to handle the data in the ETL. In the example below <em>ndcnum</em> is selected and raw NDC codes are displayed starting with most frequent (note that in the WhiteRabbit scan a “Min cell count” could have been selected and values smaller than that count will not show).</p>

 <p>Google BigQuery (GBQ) supports two different connection/authentication methods: application default credentials and service account authentication. The former method is considered more secure because it writes auditing events to stackdriver. The specific method used is determined by the arguments provided to the configuration panel as described below.</p>
 <p>Authentication via application default credentials:</p>
 <p>When using application default credentials authentication, you must run the following gcloud command in the user account only once: <code>gcloud auth application-default login</code> (do not include the single quote characters).
