Research
Compare repeated SPHEREx observations of the five targets from the Planet X and SPHEREx challenge.
Motion across epochs
- Barnard’s Star
Nearby star with high proper motion.
- Epsilon Indi B
Nearby brown dwarf binary. Compare the position of the source across visits.
- WISE 0855
Cold, fast-moving brown dwarf. Compare its position against background sources.
Brightness across epochs
- RW Aurigae
Young variable star. Compare SPHEREx visits alongside the AAVSO optical reference curve.
- R Draconis
Long-period variable star. Check the infrared measurement and coverage alongside its optical reference curve.
Comparing observations
Use Blink A/B to spot motion. For brightness changes, check the matched bandpass, coverage and quality flags before interpreting a difference image. The verification report records which measurements met those checks.
