Here’s a brief summary of what was talked about in the lightcurve breakout room in the DP0 delegate assembly 7-16-21 led by Jeff Carlin and Leanne Guy:
- A notebook tutorial is currently being written to explain how to make lightcurves.
- In the meantime, the 4th tutorial notebook - Intro to Butler, is the best resource for preparing to make lightcurves.
- Since the images available via TAP are all the 5 year CoAdd images, you can only use the src catalog to access PVIs which is available through the Butler.
(PVI - processed visit image (single visit image after processing). This is also called calexp - calibrated exposure)
To brute force a lightcurve, one could theoretically query all images with a particular track and patch and crossmatch the sources across PVIs.
- Two potentially useful notebooks which could be modified to make lightcurves for DP0 are: StackClubCourse/DataProductsToScience.ipynb at master · LSSTScienceCollaborations/StackClubCourse · GitHub and StackClub/AsteroidLightCurve.ipynb at master · LSSTScienceCollaborations/StackClub · GitHub
- This topic will be revisited in the second hour of the next delegate assembly since 30+ people attended the breakout session.
Please feel free to add anything I missed, alternate explanations, or other relevant resources to making lightcurves!
