An atlas of SWS spectra - AOT6

This table includes entries for the 23 full-scan AOT6 spectra from the Short Wavelength Spectrometer (SWS) on ISO introduced in Appendix C and Table 7 in Sloan et al. (2003). The data are available in either ASCII or FITS format. In both cases, one can download either a “pws” file, which presents the data prior to segment-to-segment normalization, with discontinuities and overlaps, or a “sws” file, which is the final version, corrected for discontinuities and with overlaps removed. The “log” file, available only in ASCII format, provides details of how the swsmake procedures generated the data files.

To read the ASCII data, one should download the IDL procedure sws6read.pro from the software page. The standard ASCII format of the “pws” and “sws” files is a header of variable length followed by the data in four-column format (wavelength in µm, flux in Jy, statistical uncertainty in flux in Jy, and finally a flux uncertainty that includes the uncertainty in normalization. The header contains one line giving the number of spectral segments and then for each segment a separate line with three integers. The second integer is the number of wavelength elements for that segment.

The FITS data are in simple FITS format (not FITS table format), with header information taken from the original ISO data files and spectral data stored as a 4-column image. Columns are defined as in the ASCII files.
