  1. MODULATION INDEX – GALACTIC LATITUDE RELATION G. Tsarevsky ASTRO SPACE CENTER, Moscow

  2. EXTRAGALACTIC SOURCES RADIO VARIABILITY

  3. EXTRAGALACTIC SOURCES RADIO VARIABILITY INTRINSIC?

  4. EXTRAGALACTIC SOURCES RADIO VARIABILITY INTRINSIC? EXTRINSIC?

  5. QSO is an essentially variable stuff!

  6. QSO is an essentially variable stuff!

  7. It should vary in radio as well !

  8. It should vary in radio as well,and it really vary!

  9. Blazar 1514+197 Green Bank Interferometer data ISS is the variation over day to week, stronger at 2 GHz Intrinsic variation is over month to year, stronger at 8 GHz.

  11. ISS Geometry From Radio Galaxy Quasar or AGN 2000 pc

  12. Center  Anticenter  Poles:↓<m>C><m>AC><m>Poles

  13. What about m - |b| plot behavior?
