SOT: HOP 101 Helioseismology
2010-09-06T18:19:00 to 2010-09-07T02:14:35
Science Goal: Helioseismology Observations of the Sun?fs polar regions with SOT
Program: Ca 4x4, 5576 DG,I 4x4 for helioseismology (Q50, Q65)
Target: N Pole
xcen=-11 ycen=890
Instrument: SOT
HOP/JOP: 101
Description:
-~1-min cadence. 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.
