Query examples
Name = 'HD2957'	Shows HD2957 data
B_mean > 100 AND SigmaB_mean < 500 AND Chi2 >= 1	Shows objects with mean effective magnetic field greater than 100 Gauss and field measurement error is less than 500 and χ² / N statistics not below 1 (NB: χ² / N < 1 means that measurements are not reliable)
ChemAnom LIKE '%Cr%' OR ChemAnom IS NULL	Shows objects with Chrome chemical anomaly or with no data about chemical anomaly
Method != 'LSD'	Shows objects with magnetic field measurement method other than LSD (Least Square Deconvolution)
TRUE	Shows all objects data
