JHKL'M photometry of northern bright stars

The final archive is made up of 10949 photometric measures through a standard InSb single-channel photometer system, principally in JHK, although some stars have measures in L'. The core of this list of stars is the standard-star list developed for the Carlos Sanchez Telescope.

A total of 298 stars have been observed on at least two occasions on a system carefully linked to the zero point defined by Vega. We present high-precision photometry for these stars. The median uncertainty in magnitude for stars with a minimum of four observations and thus reliable statistics ranges from 0.0038mag in J to 0.0033mag in K. Many of these stars are faint enough to be observable with array detectors (42 are K>8) and thus to permit a linkage of the bright and faint infrared photometric systems.
