Update on the GONG/TD LCVR temperature control issue

This is an update on the note about GONG/Teide (TD) site (Canary Islands, Spain) LCVR temperature control issue, posted back in July. Once the LCVR temperature controller was disabled on June 24th, the TD-EVT data has been stable. Science tests of the TD Doppler velocity and magnetic field images before and after the LCVR temperature control was turned off did not uncover any significant problems with the data. The GONG/TD-EVT images have been accepted for downstream processing.
