To build time-sliced spectra you must supply time ranges and names by which those spectra will be known (note, any whitespace will be replaced with '_', non alpha-numeric characters will be removed). Alternatively, you can upload a file containing a list of region names and times.
You may define up to 4 slices at a time using this form.
Times can either be seconds since T0 (see the light curve below), Swift MET, or ObsIDs. The latter should be preceeded by the word "OBS" The format is "start-stop", e.g. 150-3000 or OBS 00311607000-00311607001. You can give multiple intervals per spectrum, separated by commas, e.g. "100-350,2000-2233".
A file conforming to this standard can be uploaded here.
Here is the light curve, for reference.
