Hi Eric,
Looks to me like it hasn't been updated to use the new units code. This construction:
dt = (self.time_now - self.star_creation_time * self._ds['Time']) / YEAR
shouldn't need to access self._ds['Time'] anymore, nor divide by YEAR. It should look more like:
dt = (self.time_now - self.star_creation_time).in_units("yr")
Can you file a bug?

It's just a simple tests of spectrum generation with stars of all the same age and mass. It fails with a key error on the dataset, even thought it's not really using the dataset for anything but a reference time (I think). Since it's all small, I'll clip it in below. Here's the script itself:
from yt.mods import * from yt.analysis_modules.star_analysis.api import * ds = load("RD0009")
spec = SpectrumBuilder(ds, bcdir="/Users/hallman/work/data/sfData", model="chabrier")
sm = np.ones(100) ct = np.zeros(100)
spec.calculate_spectrum(star_mass=sm, star_creation_time=ct, star_metallicity_constant=0.02)
spec.write_out(name="spec.out")
And here is the output:
Traceback (most recent call last): File "starSpec.py", line 13, in <module> spec.calculate_spectrum(star_mass=sm, star_creation_time=ct, star_metallicity_constant=0.02) File "/Users/hallman/work/yt-x86_64/src/yt-hg/yt/analysis_modules/star_analysis/sfr_spectrum.py", line 387, in calculate_spectrum dt = (self.time_now - self.star_creation_time * self._ds['Time']) / YEAR File "/Users/hallman/work/yt-x86_64/src/yt-hg/yt/data_objects/static_output.py", line 249, in __getitem__ return self.parameters[key] KeyError: 'Time'
Even if I modify "sfr_spectrum.py" to use the key "current_time", it still fails with the same error. This is with yt-3.0, dataset created with the tip of enzo-dev as of about 20 minutes ago. It fails on older enzo datasets as well with the same error.
Thanks for any help.
