OBSERVATIONS OF THE HAWAII HDF-N FIELD
Comparison of Hawaii sample with other redshift measurements
There are 524 sources in the summary table where there are Hawaii galaxy redshift determinations (either DEIMOS or LRIS) and other measurements. (For 445 objects one of these is a TKRS measurement.) In order to check the Hawaii measurements we made a list of other measured redshifts choosing the TKRS measurement if there was one or what we thought was the best measured redshift otherwise. This comparison is shown in the figure. There are 6 substantially deviant redshifts in this figure (abs(dz) > 0.02) which are summmarized in the table below. There is also one object where the Hawaii LRIS measurement is different from the Hawaii DEIMOS measurement which is also included. Thus the error rate is less than about 1%.

189.087875 62.20236 0.7794 0.8410 (C00)
Hawaii redshift based on OII, Ca H and K, H beta and OIII
189.179794 62.18575 3.2340 0.2990 (C00)
Break interpreted as Lyman continuum break.
189.206039 62.22972 0.8520 0.0890 (TKRS)
Not clear where 0.852 redshift arises from. No sign of doubling. Hawaii LRIS spectrum gives 0.089.
189.216583 62.22564 0.9590 1.0870 (C00)
Relatively poor Hawaii spectrum
189.220337 62.23472 0.4980 1.0142 (TKRS)
Hawaii redshift based on CaK and H beta in absorption is questionable
189.233917 62.22492 1.2380 0.2710 (C00)
Hawaii redshift is poor but OIII doublet identification seems real.
