| ALGORITHM |
Description of algorithms: resol[1,2,3]_lambda: wavelengths of arc lines used for resolution calculation resol[1,2,3]: spectral resolution at three different wavelengths, averaged across slit resol[1,2,3]_rms: standard deviation of resolution across slit ids_rms: rms of global IDS He_lambda: He arc line used for determination of He lamp flux He_flux: flux of He arc lamp (ADU / mm^2 / sec) He_flux_error: error of He flux Ne_lambda: Ne arc line used for determination of Ne lamp flux Ne_flux: flux of Ne arc lamp (ADU / mm^2 / sec) Ne_flux_error: error of Ne flux Ar_lambda: Ar arc line used for determination of Ar lamp flux Ar_flux: flux of Ar arc lamp (ADU / mm^2 / sec) Ar_flux_error: error of Ar flux ids_coeff[0,1,2,3]: median values of IDS coefficients ref_lambda_pix: mean of the position of the reference wavelengths for all slits, corrected for slit position ref_lambda_rms: standard deviation of reference wavelengths position no_slit_bad: number of slits without IDS slit_width: slit width of slit closest to mask centre flux: lamp flux in ADU/sec/mm^2; calculated from the slit nearest to the CCD center in a 5 pixels x slit length wide box around the reference wavelength position flux_error: square root of total counts in box, normalised to area and time | |||||||||||||||||||||||||||
| CERTIF |
The rms of the dispersion solution should be within the range indicated by scoring. All arc lines in the extracted arc lamp spectrum should be aligned for different slits; a small number of slits may fail, the calibration for LR_blue is in general more difficult. Spectral resolution should be within the range indicated by scoring. Resolution may be outside this range if slit widths other than 1.0 arcsec are used; then search for the slit width in the pipeline products or in the QC1 database. Saturation of flat-fields for scientific slits must be avoided; up to three reference slits, however, regularly saturate. | |||||||||||||||||||||||||||
| COMMENTS |
QC parameters for wavelength calibration of MOS STDs are written into the vimos_mos_stdmask_wave table, others into vimos_mos_wave. The combination of MR grism with OS-blue filter is not supported by the pipeline. | |||||||||||||||||||||||||||
