Added a network paramter to all list of Observatories and Variometers. I made this a non optional paramter within Observatory.py.

Added the previosly deleted line is_gin: False back to the the ObservatoryMetadata file for the YKC observatory.

Revised the minute definition in ObservatoryMetadata and VariometerMetadata. Removed the ObservatoryMetadata variable from IRISFactory and replaced it with the VariometerMetadata variable and an optional variable that points to the VariometerMetadata module.

Updated the IRISFactory to support the new VariometerMetadata class. Also removed unnecessary lines of code in VariometerMetadata.py and ObservatoryMetadata.py.

Updated the ObservatoryMetadata and Observatory.py files to point to the default_metadata dictionary only. Also edited the declination_base argument so that it defualts to an int = None rather than 0. This change is reflected in the default_metadata as well. Anywhere declination_base didn't exists or equaled 0 is now set to 'declination_base' = None

Adds support for FGE volts channel from BDT. Edits observatory metadata with scaling and FGE parameter added.

Adds KAK into observatory metadata's dictionary definition.

Adds KAK into observatory metadata dictionary.

These changes were deployed directly to production (mage2) on November 8. This is a belated update to the official metadata.

Saint John's -> St Johns
Yellow Knife -> Yellowknife

Discovered a small typo in the BLC (Baker Lake) entry. Fixed it.

Only the BOU observatory had updated DECBAS values. This commit includes all DECBAS values adopted on July 1 2013, which estimated from the 2011 annual means. These values have been used in the preliminary data exported to Intermagnet since they were adopted, but they have not been used in geomag-algorithms.

We recently reviewed our various data products and found discrepancy in some of the metadata.  We have updated these values based on recent measurements.  I've modified these values in ObservatoryMetadata.py to be consistent with our other data products.
