Individual notes:
G026-012: K not measured at TCS has been assigned with Carney 1983
(AJ 88, 610), given the good agreement for J and H.
G033-009: (V-K) too large, probable misidentification.
G036-050: The two measurements in J differ in 0.2 mag.
G106-049: Variable, {DELTA}J=0.2, {DELTA}H=0.16, {DELTA}K=0.13.
G124-023: Misidentification.
G208-029: Variable?
HD128959: The two measurements in J differ in 0.16 mag.
HD188510: Only one measurement in K.
HD74000 : Unknown star measured instead HD74000.
HD227638: Unknown star measured in the same field J=8.425 ±0.035 ,
H=7.810 ±0.014 , K=7.690 ±0.014.
HD229274: Variable?
