FLOW SODISM SCIENCE TM

They are two compression on boardLossless compression (PLLC)With degradation (Langevin)

The compression rate of PLLC depend of the noise on the pixels of CCDSo the commissioning period allow to define the size of limb PLTMand macro-pixels

The perspective is to allow about 51 pixels of large for the diameter measurements

SODISM Filter wheels from 01/08 to 30/09

Pm : 2 steps correspond to 0.2 mm to 0.5 mm of movement on the filter

When they are new requirements on the payload, the only possibility is to try to treat them, with the operational software

2 problems now1) SOVAP: it become necessary to prevent all telecommand that closethe right shutter2) SOVAP : This requirement can becomes obsolete if need3) SODISM : Necessity to have full images compressed by Langevin with filters helio

Point 1 and 3 will be treated thanks to a new version of the software (planning max February 2011)Point 2 will be treated by a patch of the memory (very easy processes)
