Just a 1 cent thought that may not apply or be accurate.
C-fields are current sensitive, so if they are wound with copper wire, any
small change in their temperature, even when temperature controlled, could
have a effect much greater than 1PPM on that current when driven from a
fixed voltage thru a resistor.
Does anyone use current drive?
Attached is the schematic of the C-field supply.
