+The 2D ASCII output files of SANS data are of the format below. It is simply a dump of the detector pixels that may or may not have gone through any correction steps. What corrections have been applied to the data depend on what (if any) reduction steps were applied before exporting the file.
+
+In each file there is a header of information describing the sample information (gleaned from the raw data file) and information about the processing steps that were taken to generate the reduced data file. The data is in a single column format of detector counts (or corrected counts):[[BR]]
+
+The 2D detector is a normal XY coordinate system when viewed from the neutron source. The single column of data is written row-wise, starting with Y=1 and X=1->128, that is starting from the lower left corner of the detector and working to the upper right. The current detector is square, 128x128 pixels.
+
+No errors are currently carried with the data.
+
+(only a snippet of the file is shown here)
