The 1D output files of reduced USANS data are of the format below. 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 6-column format where the 6 columns are:

1- q (1/Angstrom)
2- I(q) (1/cm)
3- standard deviation of I(q) (1/cm)
4- (-1)dQv, the slit height (1/Angstrom)
5- (-1)dQv, the slit height (1/Angstrom)
6- (-1)dQv, the slit height (1/Angstrom)

Note that the (-) sign on the slit height in column 6 is used as a flag for the data reduction program to recognize slit-smeared rather than pinhole data. Columns 5 and 6 are dummy placeholders.

In the XML export of USANS data, dQv is reported as a positive value.

(only a snippet of the file is shown here)
