11.3	Additional COS Files

Several additional files are used in the processing of COS data. These include association files (asn), which are used to control calibration processing; engineering support files (spt), which contain information used in the pipeline processing; and lampflash files (lampflash), which contain extracted wavelength calibration spectra used in the processing of TIME-TAG data with FLASH=YES. For a full description of these and other files, see the COS Data Handbook.
