  1. DATA MINING Workshop Nantucket October 17, 2008

  2. Some Useful Past/Current Surveys and Databases • microlensing (EROS, MACHO, OGLE); small area-bulge-LMC, 1 image/day/field for years • asteroids (LONEOS, LINEAR,CSS); ecliptic, 1000’s deg/night,shallow • other wavelengths (X-ray[HEASARC], UV[MAST], IR[IPAC], radio[NRAO]): sporadic • variability (FSVS [23 sq deg, 24 mag], DLS[4 deg2, 5 yrs], SDSS Stripe 82 [300 deg2, 7 yrs], SCP [SN], ROTSE, ASAS [GRB], Palomar-Quest [500 deg2/night]) Upcoming Future Surveys • Pan-Starrs(Hawaii) -2009 start with one 1.8m, 3 more planned, 6000deg2/night; 3 times/month, 24th mag • LSST(Chile) - 2015 start, 8.4m, 20,000 sq deg 1000 times over 10 yrs, 27th mag - 50 million variables predicted

  3. Some Advantages of Databases:

  4. Some Advantages of Databases: • gives you something to do on cloudy nights

  5. Some Advantages of Databases: • gives you something to do on cloudy nights • gives you sky access with no equipment

  6. Some Advantages of Databases: • gives you something to do on cloudy nights • gives you sky access with no equipment • gives you a lot of information you cannot get from the ground (space databases)

  7. Some Advantages of Databases: • gives you something to do on cloudy nights • gives you sky access with no equipment • gives you a lot of information you cannot get from the ground (space databases) • there is a lot of data

  8. Some Disadvantages of Databases:

  9. Some Disadvantages of Databases: • there is a lot of data

  10. Some Disadvantages of Databases: • there is a lot of data • it may not be easy to access it

  11. Some Disadvantages of Databases: • there is a lot of data • it may not be easy to access it • it may not be the cadence you want/need

  12. Some Disadvantages of Databases: • there is a lot of data • it may not be easy to access it • it may not be the cadence you want/need • you don’t know the details of night,etc
