Galaxy Templates

As a first step to comparing the SEDs with models, it is helpful to first compare with galaxy templates. A small set of galaxy templates from Kinney and Calzetti have been made available on a URL and accessible via the following SSA file. This means that the SSA file may be loaded into the AVO prototype and the template spectra plotted in specview.

(The template files are in specview .txt format)

First stab at a Groovy translation

At the moment, it's framed as a script that you run from the commandline - just like the original IDL. Later we need to work out how we want to chop it up, put it in a workflow, and attach it to cea tools and myspace.. But for now, this script proves the feasability of doing the processing in groovy.

To execute the script, you'll need to download and install the astrogrid commandline bundle - http://software.astrogrid.org/client-install.html

Differences:

• The groovy script starts with the votable returned from Vizier, rather than the pre-cooked .dat files used by IDL. I think this is a bonus.

• The output generated by the groovy translation is pretty close to the original - in places the files produced by groovy contain numbers with a larger number of decimal places, but the values are the same (modulo rounding)

• The generated votables are similar, but have som minor differences too. Could someone test the generated files by feeding them into whatever they're meant to go into next, and let me know if there are any problems.

Unsure of..

• Whether I'm extracting coordinates from the votable in the correct format. The IDL input files have different columns to the vizier votable.

• There's one point where the IDL script uses the function 'alog10'. Groovy/Java doesn't provide base-10 logs, only natural base logs. I've

• In the original IDL, there's a bit that says..

; Red, z<0.5, and detected in all optical bands
group1 = where(  ((am3 - am4) gt 0.8) AND ((am2 - am3) gt 1.2) AND (spectz gt 0.0) AND (spectz lt 0.5) AND (am1 gt 0.0) AND (am1 gt 0.0) AND (am2 gt 0.0) AND (am3 gt 0.0) AND (am4 gt 0.0) AND (am5 gt 0.0) )
