A resulting velocity looks very good with 15km/s for an input spectrum of 18km/s.<br/> The resulting pfsZcandidate*.fits file, however, contains only 2 HDUs instead of 5 and therefore does not contain uncertainty and posterior probabilities for the redshift. The contents of the output files look like:</p> <p>No.  Name   Ver  Type   Cards  Dimensions  Format<br/>  0 PRIMARY    1 PrimaryHDU   10  ()    <br/>  1 ZCANDIDATES  1 BinTableHDU   21  1R x 6C  <span class="error">&#91;D, D, J, D, 15A, 15A&#93;</span> </p> <p> </p> <p>When I set “enablestellarsolve = no”, an output pfsZcandidate*.file properly contains 5 HDUs, but when I set “enablestellarsolve = yes”, an output file contains only 2 HDUs. It would be great if the drp_1dpipe contains additional HDUs also for stellar analyses. </p> <p> </p> PIPE1D-25

Indeed the PDF is only computed on the very short redshift range  <span class="error">&#91;-0.001;0.001&#93;</span>, the model is only the template, and we do not perform line measurements on stars. </p> <p>For consistency, we will include those HDUs within this branch</p> <p>Vincent</p> <p>Dear Vincent, </p> <p>Thank you for your comments! Yes, that would be very helpful. For the stellar solver, I set</p> <p>"redshiftrange" <span class="error">&#91;-0.001; 0.001&#93;</span>,  "redshiftstep" 1.0e-6. Is this very small step compatible with the pipeline algorithm?</p> <p>Well, all steps values are theoretically OK, but the computation time will increase. It should remain OK as the resdshit range is small</p> <p>Vincent</p> <p>Thanks for the confirmation. Then, we will, at the moment, continue using  "redshiftrange" <span class="error">&#91;-0.001; 0.001&#93;</span>,  "redshiftstep" 1.0e-6 for stellar analyses. </p> Relates DAMD-92 Development Rank 0|zzs2s8: Reviewers ishigaki
