Similar to HOP330 on 2017 April 22 at 14UT, but twice as wide (i.e. 20"). *********** SOT 330 request *************** Fast Hinode/SP rasters with a cadence of maximum 80s. Readout along the slit should be at least 60 arcsec. FOV perpendicular to the slit should be densely covered. The program can be very similar to that of HOP 243: SP: very fast maps, to obtain the required time resolution with enough slit positions to maximize the chance of overlap with the IRIS slit. Both sides of the CCD are used to increase SNR.
Two programs have been tested so far: SP 0x15b Very Fast Map, 9"x82", 2-side CCD, Q65, repeats: cadence = 73 sec, telemetry usage = 500 Mbits/hour SP 0x190 HOP 243 low-TLM, Very Fast map 9x82, lower half For a plage target observed with IRIS, use either SP 0x0194 HOP 243 Plage, DynamicsMode 9x82, bottom half, uses ~1000 Mbits/hr SP 0x0195 HOP 243 Plage, Lower-TLM DynMode, 9x82, bottom half, uses ~500 Mbits/hr ***************************************************** |
