2. Calibration Channel
... An internal flat field system provides reference flat field images over the spectral range of WFPC2. These are provided by a "calibration channel" optical system mounted outside the main shroud of WFPC2. ... The flat field illumination pattern is fairly uniform for wavelengths beyond about 1600 . Short of 1600 the flat field is distorted due to refractive MgF2 optics. ... The calibration channel is used primarily to check for internal instrumental stability. ...

5. Spectrum-response channel range matching
... Fitting packages such as XSPEC do not allow the channel range of the spectrum and that defined in the RMF to differ. ... If the channel range of the spectrum and that of the reponse data obtained from the CAL are found to differ, rmfgen raises a warning and performs one of the following corrective actions: . ... If the channel range of the spectrum is a subset of the response range, rmfgen will truncate the response data to match the channel range. ...

10. Robust, Realtime Bandpass Removal for the HI Parkes All Sky Survey Project
... We present the algorithm and implementation details for the robust, realtime bandpass removal and calibration routine developed for the HI Parkes All Sky Survey project. ... Traditionally, the bandpass that is present in single-dish 21 cm spectra is removed by observing in a ``signal-reference'' mode. ... The robust bandpass removal algorithm implemented for the HIPASS Project successfully produces calibrated HI emission line spectra for most of the survey data. ...

11. Calibration of visibility amplitudes and closure phases
... C ALIBRATE V ISIBILITY : Select PLOT, and flag first the channels since their SNR is usually very low (if you observed with the 3-way system; the 6-way system has only 16 channels). To do this, plot VisSq vs channel, selecting all channels and the All-in-1 option. Then, for calibration, look at the data from the calibrator stars (select them using the information in the StarForm), then select CALIBRATE to display the calibration widget. ...
