## ## Sparse Single-Pointing unaveraged spectra ## ## ## Rosalind Hopwood ## ESAC SPIRE Instrument and Calibration Scientist ## ## 4th November 2016, v1 ## # Description of UPDP The unaveraged spectra UPDPs are data products that have been fully processed with the SPIRE Spectrometer standard product generation (SPG) pipeline, except the averaging step has been omitted. This means that for each detectors in a given observation, the UPDP contains all of the individual forward and reverse scans. The data were reduced with HIPE version 15.0, using spire_cal_14_3. There are unaveraged products for all observations taken in Sparse, Single-Pointing mode. The data are point-source calibrated in flux density units of Jy and presented in the same format as their averaged HSA counterpart. Each product is provided as a gzipped FITS file, which are named with the convention: "OBSID_unaveraged_RES_pointSourceSpectrum.fits.gz" where OBSID is the observation identification number. RES is the resolution of the observations. Either HR or LR. Both resolutions are available for observations taken in H+LR mode. The files size ranges from 56 KB to 375 MB. You can find the FITS extensions that correspond to the centre detectors using the respective names, i.e. "SLWC3" and "SSWD4". The FITS extension names (EXTNAME keyword) correspond to the name of the detectors, so the unaveraged spectra for the two central detectors are in extensions "SLWC3" and "SSWD4". # Purpose These data have been made available so that inspection and analysis of the constituent scans of the standard averaged product (in the HSA) is possible without rerunning the pipeline. # Caveats Note that the following observations are considered as "Failed" due to poor calibration or due to high pointing offset from the intended on-sky position. If you are considering inspecting any of these, it is important to read the accompanying quality control summary. # "Failed" observation IDs 1342188185 1342193810 1342193811 1342193661 1342193662 1342193666 1342202272 1342208381 1342208382 1342208383 1342208384
