Preliminary minimal requirements on the photometric and spectroscopic follow-up of Gaia Alerts
- multi-band photometry, at least two bands (e.g. V,I), Sloan ugriz preferred
- flux calibration no worse than 10% (0.1 mag)
- availability of flux measurements within less than couple of hours
- spectral range minimal: 4500-7000A
- signal to noise > 20 all over the range above
- resolution R > 150
- lambda calibrations better -+ 3A
- relative flux calibrations better -+10%
- absolute flux calibrations: none
- availability of reduced spectra within less than 12h
Current and future instruments suitable for Gaia alerts response
Please expand this list with information on the telescopes/surveys which might be suitable and interested in Gaia alerts follow-up and in operation in years 2012-2017.
Hessman's list of (mainly robotic) telescopes (including ones in preparation).
- MASTER Robotic Net (Lipunov et al. 2009) limiting mag= 19-20, started in 2002 in Moscow, Russia, followed-up many GCN alerts; now being upgraded to a network all over Russia (1000 clear nights per year).
- 3 telescopes operated at the Konkoly Observatory, Piszkesteto Mountain Station  (Hungary): 50 cm Cassegrain, 60/90/180 cm Schmidt, 1m RCC.
