Appendix H
Quality Assurance Parameters

Quality assurance parameters are supplied via the command line option -cal qaparams=<qa.ini>. For an example QA parameters file see Section 6.3.




Parameter

Description



BADPIX_MAP

Maximum fraction of pixels allowed to be bad in the final map.

GOODRECEP

Minimum number of working receptors

TSYSBAD

Upper limit of Tsys for raw time-series data.

FLAGTSYSBAD

Flag any receptor with >FLAGTSYSBAD of data points with Tsys > TSYSBAD

TSYSMAX

Median Tsys > per receptor after flagging by FLAGTSYSBAD must be <TSYSMAX

TSYSVAR

Maximum allowable receptor-to-receptor Tsys variation

RMSVAR_RCP

Maximum allowable receptor-to-receptor RMS variation

RMSVAR_SPEC

The average rms noise shall not vary by more than RMSVAR_SPEC from one end of a spectrum to the other.

RMSVAR_MAP

The rms noise in the map over the region with uniform sampling shall not vary by more than RMSVAR_MAP from one pixel to the next.

RMSTSYSTOL

The rms that is measured for each receptor should agree with the value expected from the system temperature, spectral resolution, and integration time to within RMSTOL.

RMSMEANTSYSTOL

Data with an RMS > RMSMEANTSYSTOL% of the mean RMS will get masked out.

CALPEAKTOL

Observations of the spectral-line calibrators shall agree with their expected values for line peak intensity to within ±CALPEAKTOL.

CALINTTOL

Observations of the spectral-line calibrators shall agree with their expected values for integrated intensities to within ±CALINTTOL.

RESTOL

Remaining residuals after subtraction of the baseline shall be no larger than σ×RESTOL on average.

RESCHAN12CO

Channels over which to average for residuals for a first line (12CO here).

RESCHAN13CO

Channels over which to average for residuals for a second line (13CO here).

RESTOL_SM

Remaining residuals should be no larger than σ×RESTOL_SM on average over any four adjacent channels.

VELRES_12CO

Velocity resolution for the first line (12CO here).

VELRES_13CO

Velocity resolution for the second line (13CO here).
