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:</div><div><br></div><div><div>from yt.mods import *</div><div>from yt.analysis_modules.star_analysis.api import *</div><div>ds = load("RD0009")</div><div><br></div><div>spec = SpectrumBuilder(ds, bcdir="/Users/hallman/work/data/sfData", model="chabrier")</div><div><br></div><div>sm = np.ones(100)</div><div>ct = np.zeros(100)</div><div><br></div><div>spec.calculate_spectrum(star_mass=sm, star_creation_time=ct, star_metallicity_constant=0.02)</div><div><br></div><div>spec.write_out(name="spec.out")</div><div><br></div><div><br></div><div>And here is the output:</div><div><br></div><div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">Traceback (most recent call last):</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> File "starSpec.py", line 13, in <module></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> spec.calculate_spectrum(star_mass=sm, star_creation_time=ct, star_metallicity_constant=0.02)</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> File "/Users/hallman/work/yt-x86_64/src/yt-hg/yt/analysis_modules/star_analysis/sfr_spectrum.py", line 387, in calculate_spectrum</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> dt = (self.time_now - self.star_creation_time * self._ds['Time']) / YEAR</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> File "/Users/hallman/work/yt-x86_64/src/yt-hg/yt/data_objects/static_output.py", line 249, in __getitem__</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"> return self.parameters[key]</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">KeyError: 'Time'</div></div><div><br></div><div><br></div><div>Even if I modify "sfr_spectrum.py" to use the key "current_time", it still fails with the same error.
