pcaphasyserr - Apply systematic error for PCA spectrum
pcaphasyserr myspectrum.pha pculist layerlist [syserrfile=CALDB]
pcaphasyserr applies the PCA team-recommended systematic error to a PCA spectrum.
The user must have an existing PCA spectrum (any data mode). The file is modified in place.
Upon output, the SYS_ERR column is created and is filled with the recommended systematic error due to response uncertainties. Note that this does not include background systematics.
By default, the systematic error file is retrieved from RXTE PCA's Calibration Database (CALDB), although a file name can be specified manually as well.
This example applies systematic error estimates to a spectrum generatd from all PCUs, layer 1 only.
pcaphasyserr myfile.pha ALL 1
This example assumes all layers were used.
pcaphasyserr myfile.pha ALL ALL
This systematic error estimate is not perfect.
