Station:
Private observatory, Lombardy, Italy
Lat: +46°, Long: +09° - Instrument: RC 203 mm + TS 0.67x reducer (f/5.6), IMX571 mono, Baader Sloan filters
- Photometric band: Sloan r'
- Time standard: BJD_TDB
- Brightness in: Mag
Note:
Forced aperture photometry (position from WCS) on co-added runs of 2-3 x 10 s frames; ensemble of ~150 Gaia DR3 GSPC comparison stars (synthetic SDSS). Untransformed. Absolute level uncertain by ~0.05-0.1 mag (position-dependent illumination correction outdated); timing unaffected. Our own fit of this secondary minimum (symmetric polynomial, bootstrap errors): BJD_TDB 2461288.47481 +- 0.00180 d.
