I’m working on simulating SNIa objects that the LSST is expected to detect. For one part of the simulation I would like to generate the galactic coordinates for simulated objects.
Unfortunately, I can’t seem to locate information that would allow me to appropriately construct a sky density field that I could sample galactic coordinates from. The closest is the Kaggle PLAsTICC challenge here which provides simulated data for many classes of objects
I could use the Kaggle data to estimate the sky density field using the provided data for the challenge (using the train or test set? the datasets are imbalanced) and then draw coordinates for SNIa objects using that. I’m not sure if that would be appropriate or not in case the current survey strategy has changed enough since the challenge such that the expected sky density distribution of objects is now deemed to be significantly different from that provided by the Kaggle challenge.
Any comments/suggestions are very welcome!
