BPZ Test

To verify that your installation of BPZ is working properly.

In ~/bpz-1.99.3/test/ run the following:

bpz UDFtest.cat -INTERP 2
python $BPZPATH/bpzfinalize.py UDFtest
python $BPZPATH/plots/webpage.py UDFtest

Check the output:
~/bpz-1.99.3/test/html/index.html
It should look like this

Intermediate output (can all be checked against the results in test/output/ ):
You may now wish to proceed to Quick Start or Manual.


Or you may wish to run another test: on all objects with spec-z in the UDF (as of 2006).  Here you will test whether the photometry has been well calibrated.  You will rediscover the photometric offsets in the NICMOS J & H bands (Coe06).

bpz UDFzspec.cat -INTERP 2 -ONLY_TYPE yes

By setting -ONLY_TYPE yes, BPZ will use the known spec-z, fitting only for the SED type.  The command line output will also report large photometric offsets (-0.247, -0.102) in J & H, respectively.  (This automated routine has not been tested extensively, but these offsets are comparable to those found in the more careful analysis of Coe06.)   These offsets should be entered into the .columns file (to be added to the magnitudes) and BPZ re-run.  We supply the modified .columns file for you:

bpz UDFzspec.cat -INTERP 2 -COLUMNS UDFzspec_mod.columns
python $BPZPATH/bpzfinalize.py UDFzspec
python $BPZPATH/plots/webpage.py UDFzspec -DIR htmlall

This results webpage should take about a minute to generate.  When finished, it will be found at:
