Missing QARTOD flag variable results

[kerfoot]

I searched through the open issues but did not find anything specific to this, so I'm filing a new issue. I was checking the QARTOD results for a glider that we currently have in the water maracoos_06-20250116T1522.

The following qartod variables are filled entirely with NaNs/_FillValue:

• qartod_density_flat_line_flag
• qartod_density_gross_range_flag
• qartod_density_primary_flag
• qartod_density_rate_of_change_flag
• qartod_density_spike_flag
• qartod_salinity_flat_line_flag
• qartod_salinity_gross_range_flag
• qartod_salinity_primary_flag
• qartod_salinity_rate_of_change_flag
• qartod_salinity_spike_flag

This appears to be the case for many of the active real-time data sets on the DAC ERDDAP server.

Does this mean that the these tests were not run by the DAC? If not, what does it mean? I would assume that, at a minimum, the *salinity* flags are required by NDBC to omit bad salinity values, but they are not available.
