IZMIRAN's   Solar Digital Meter Observations

by  Gorgutsa R.V.,   Gnezdilov A.A.,   Markeev A.K.,   Sobolev D.E.

Radiospectrograph:

frequency range             25 - 270 MHz

time resolution               0.04 s (0.02 s alert)

frequency resolution       0.2 MHz

intensity dynamic range   ~1- - ~10000 s.f.u.
(it's ajusted depends from a task)

data convert to FITS, IDL - processing is avaliable too

Fixed frequencies radiometers:

frequencies                   169 MHz, 204 MHz, 3000 MHz

time resolution                  1 s

intensity dynamic range   ~1 - ~100000 s.f.u.

Observations:

daily spectral observations - since 1967

digital registrations -       since late 1996

observations time:
      patrol   06 - 12 UT   ( 07 - 12 UT in winter )
      alert     04 - up to 18 UT ( June )

Alert observations (additional device):

- high time resolution radiospectrograph
    frequency range       220 - 260 MHz
