Description
Supplementary material to DESI's publication "Target Selection for the DESI Peculiar Velocity Survey" to comply with the data management plan.
Contains data for
Figure 1: color-color diagram, comparing truth catalogues to data from the survey. Data contains all observational colors to construct the heatmap and the colors of the two truth catalogues shown in the left and right panel respectively.
Figure 2: Sersic index for different morphological types. Data contains relative number counts to reproduce the histogram.
Figure 3 consists of images, hence not included here.
Figure 4: quality metrics for ETG classification. Data includes the various metrics as a function of elliptical probability.
Figure 5: Success rate for different magnitudes. Data contains all the plotted data points as a function of magnitude.
Figure 6: pPXF example for ETG: Data contains the plotted spectrum and model.
Figure 7: quality metrics for LTG classification. Data includes the various metrics as a function of spiral probability.
Figure 8: example for TF measurements: Data contains the two spectra shown in the figure.
Figure 9: example of rotation curves from MaNGA: Data contains the individual measurements, fit, and shown example.
Figures 10 + 11: comparison between the observed rotational velocities and calculated one. Data contains DESI and MaNGA measurements as well as expected values from the fit.
Figure 12: Sky distribution of PV surveys. Data contains the coordinates of the targets of all the surveys shown.
Figure 13: Redshift distribution of different PV surveys and our targets. Data contains the number counts to reproduce the histogram.
Figure 14: Forecast for f-sigma8 constraints. Data contains the predictions from different theories and the forecast for DESI (PV and/or BGS).
Figure 15: Forecasts for measurements of the velocity power spectrum. Data contains the forecast for the DESI.
