Study 000177: ACRONYM: ardiag_sns This study is intended to be run on an active region. It begin by taking a context raster with the 40" slot of the active region. The study ardiag_sns_1 then moves to a sit and stare mode with the 1" slit to obtain high temporal cadence data (10 secs) of a particular point along a visible loop structure within the active region. Either the apex or the footpoint of a structure is preferable depending on what can be seen. The duration and data rate for this study is 52mins 52secs and 30.02 kbps respectively. The context raster is then run again at the end of study. The DCPM (lossless) data compression scheme is used for the study. If the active region is on the disk, SOT magnetograms are required. At all times concurrent XRT data is required. WARNING: 1) Multiple SLA use 2) This study uses 1, 10s exposure raster, repeated 200 times. Raster synchronisation needs more time time. **** Add 10% to the study run time **** and re-adjust % if necessary.
