| dc.description | New near-infrared galaxy counts in the J and K bands are presented over a total area of 0.70 and 0.97 degrees^2, respectively. The limiting magnitudes of the deepest regions are 19.5 in J and 18.0 in K. At J>16 and K>15 our J and K-band counts number counts agree well with existing surveys provided all data are corrected to a common magnitude scale. There are real differences from field to field, and the ELAIS N1 and N2 fields show an overdensity of J<16, K<15 galaxies. The slopes of log N(m) / dm are 0.40 to 0.45 at 15<K<18 and 16<J<19.5. Our counts favor galaxy models with a high normalization of the local luminosity function and without strong evolution. | |
