3. Error and Bias in the STSDAS fitting Package
... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ... Results show that both methods may generate biased coefficients (at the ~few percent level), and over or under-estimate error bars (at the ~10 percent level), in particular from low signal-to-noise data. ... Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...

10. Measurement Errors
For a sample of 16 people, the error would be 4/16 = 25%. This a large error since the range of YES vs NO is from 0-100% if 12 people answered yes and 4 people answered no then your result would be: . Percentage yes = 75 +/- 25% . ... For a sample fo 1000 people, the error would be SQRT(1000)/1000 = 33/1000 = 3%. If 750 answered yes and 250 answered no then your result would be: . ...

You can check what the catalogue thinks it knows about the pulsar by using psrinfo and typing . ... NSUB: - Number of frequency sub-bands . ... Note if you are reducing this data at Parkes you will have to copy psrcat.unformatted back up to $PSRHOME/soft/psrinfo at Parkes before rerunning tarchfb_driver. Back to the Filterbank data reduction page. ...

16. Keywords_262
... First, we computed the mean errors of orbit parameters on the assumption of the linear connection of them with observation errors and then we compared obtained estimates with those resulting from the assumption of the nonlinearity of this connection. Secondly, we correlate orbital parameters and their errors obtained by the method of the least modulus with those obtained by the least-squares method. ...

19. Calibrating amplitude errors
. Next: Unwrapping triple phases Up: Calibrate data Previous: Scan data Contents . The errors on the amplitudes of the visibility and the triple can be recomputed based on their formal uncertainties and the calibration error. The latter is derived from the variation of the calibrator visibilities and the comparison to their formal errors. Both are added in quadrature. This procedure requires the selection of calibrator and program stars. Christian Hummel 2015-04-28

20. Plug-and-Play-HOWTO : Error Messages
Next Previous Contents . This means that an interrupt happened that no driver expected. ... In many cases you can safely ignore this error message, especially if it only happens once or twice at boot-time. For boot-time messages, look at the messages which are nearby for a clue as to what is going on. For example, if probing is going on, perhaps a probe for a physical device caused that device to issue an interrupt that the driver didn't expect. ...
