Constant cadence is highly required for our helioseismology analyses. -Continuous observation for 16 hours at least. -The limb should be included in the field of view for co-alignment. -The field of view should be fixed. No tracking. -NFI: Fe I 557.6nm Dopplergram (if telemetry allows) -BFI: Ca II H (this is the primary data set) -If NFI takes 1024x512 Dopplergrams (Q65) with 4x4 summing and BFI takes 2048x1024 images (Q50) with 2x2 summing program ID: 0x1f5, (see below, however), estimated data volume is 1.2 Gbits for 16-hr run. (Note: this is the reduced telemetry version, original used 3.13 Gbits.) -If we use only NFI, taking 2048x1024 Dopplergrams with 2x2 summing, estimated data volume is less than 450Mbits per hour if the compression factor is set at Q75. ivo://sot.lmsal.com/VOEvent#2010-09-06T18:19:00Z
