IRAC photometry -- The SED templates supplied in this release are undefined beyond 25,600Å. Thus they are extrapolated (poorly and too low) at these wavelengths. Photo-z are pushed out to z > 0.4 for low-z objects with IRAC photometry. We advise against using IRAC photometry in photo-z estimation as they provide little (if any) benefit, regardless of the analysis method used (Hildebrandt10). If you do use IRAC photometry, please use a template set which covers those wavelengths. (Users may inquire if we have updated templates useful for this purpose.)
Stars / AGN -- We do not attempt to discriminate among normal galaxies, stars, and AGN.
Prior undefined for i < 20 -- Performance for bright objects can be affected (-Sam Schmidt 12/9/08). Brighter objects are assumed to have i = 20 for the purposes of the prior.
Interpolation between SED templates -- between fluxes (not normalized?) rather than magnitudes as in other methods (-Sam Schmidt 12/9/08)
-N_PEAKS >= 2 bug for zb ~ 0.01 ? -- Objects assinged zb ~ 0.01 are also assigned: zbmin = 0.08, zbmax = 0.01 (-Marc Rafelski 3/9/09)
Very special thanks to Marc Rafelski, Sam Schmidt, and Perry Gee for
extensive testing, pointing out issues, and uncovering bugs in earlier
versions.
