Finding bursts: the routine iris_burst_check.proThe IDL routine iris_burst_check.pro runs through an IRIS spectral data-set and identifies which pixels qualify as bursts. For each pixel, the routine checks
The second requirement aims to prevent intense particle hits
(which
usually occupy only one or two spectral pixels) from being flagged. The
threshold value is determined as follows:
Calling sequenceThe routine is available in the IRIS Solarsoft distribution and it is called as: IDL> iris_burst_check, filename [, output=, threshold=, /no_median, ixrange=, /quiet] OUTPUT: a structure containing information about each pixel that passes the threshold. ExampleThe data-set of Tian et al. (2016, ApJ) from 2-May-2015 02:34 UT is used as an example. IDL> file=iris_find_file('2-may-2015 02:34') The output text displays five events, with the time, X-index,
Y-index and intensity corresponding to the brightest pixel of the
event. The number of pixels belonging to each event is indicated. The
threshold value for the detections is displayed. Page maintained by Dr Peter R Young. |
