ObsCore: o_ucd for uncalibrated data?

Hi Alberto ,
Considering your email again , and the following ones along the same
thread ,
in Obscore you have various optional fields available to describe the
observable axis, as shown in Table 7 p. 59:
o_unit adql:VARCHAR NULL NULL Char.ObservableAxis.unit meta.unit
o_calib_status adql:VARCHAR NULL NULL
Char.ObservableAxis.calibrationStatus meta.code.qual
o_stat_error adql:DOUBLE NULL $(o_unit)
Char.ObservableAxis.Accuracy.StatError.refval.value stat.error;$(o_ucd)
where $(x) means the content of the x variable, here o_unit or o_ucd
in addition to o_ucd .
this then allows to clarify the calibration status of each axis.
This should appear in Table 5 , "Data model summary", but I don't see it.
I suppose I had a wrong cut/paste operation while updating the new
Obscore 1.1 version .
I correct this.
Thanks for raising this point .
Best wishes , Mireille
