Notes:
(1) The estimated uncertainties are 3% at JHKLL', 6% at M, 3% at N, and 5% at Q.
(2) The flux density for 0.5556 um is from Hayes (1985).
(3) The "reference wavelengths" (i.e., monochromatic wavelengths) of the IRTF N and Q filters are 10.1 and 20.0 um for standard stars.
(4) flambda is given in MKS units for consistency. This unit is widely used outside the US and it is a better unit for posterity.
