DIF-C-HRII-2-EPOXI-GARRADD-V1.0 Raw Data DIF-C-HRII-3/4-EPOXI-GARRADD-V1.0 Calibrated and Resampled Data Review Result: Certified. Symbol Key: o = Lien open x = Lien resolved or closed ! = Lien rejected + = Comments (by SMcLaughlin unless otherwise indicated) Catalog ======= ! In the dataset.cat file description, please add full citations to the Calibration papers (i.e., as footnotes in the text in addition to the REFERENCE objects that also exist). + Rejected by PI and archive lead. The correct and full citations are already in ref.cat. + There needs to be a reference to the source of the pole definition for Garradd and ISON in some appropriate place. [Note that the SPICE kernels likely involved have not been reviewed.] + Done. x There is a known issue with a solar flare that significantly affects data on a particular date. This should be noted in the data set descriptions for all affected data sets. + Not relevant. HRII spectra not acquired during/about solar flare in early March 2012. Only VIS data are affected. x In dataset.cat. the CITATION_DESC year must be '2014' since this is when the data were reviewed and released to the public. + Done. x In the dataset.cat DESCRIPTION, the description of the scanning process is confusing and needs to be re-worded. + Already done. The project feels the description as provided by L.Feaga is clear, and the reader is referred to Feaga, et al. (2014) where the observing technique is further described. Documents ========= x Ensure these data sets have the latest versions of these document files: day_of_year_calendar.lbl epoxi_cal_pipeline_summ.lbl epoxi_sis.lbl instruments_hampton.lbl pdsdd_epoxi.lbl quaternion_desc.lbl + Done. x In epoxi_sis.pdf: x This document says labels for HRIV, MRI, and ITS level 3/4 data, PDS keyword PROCESSING_HISTORY_TEXT contain FLAT_PRO= FLATCONS= FLATTEMP= CALWINDW= CALWINPY= but the sample labels in the SIS's 4.4.4.1 and 4.4.4.2 do not. x p. 27: "DIF-L-HRII-3_4-EPOXI-LUNAR-CALS-V1.0" should have a / not a _ i.e. "DIF-L-HRII-3/4-EPOXI-LUNAR-CALS-V1.0" x epoxy_sis.pdf pages 47-9 the figures are misaligned with the text. This needs to be corrected in every copy of the document in all data sets. + Done, except for the item about PROCESSING_HISTORY_TEXT. That PDS keyword will contain different processing keywords because the calibration pipeline performs different steps for the VIS HRIV, MRI, and ITS CCDs and the IR spectrometer. For example, the FITS header keywords FLAT_PRO, FLATCONS, FLATTEMP, CALWINDW, & CALWINPY only apply to IR calibration, so those values are never included in PROCESSING_HISTORY_TEXT. However, we noted this difference in the description of PROCESSING_HISTORY_TEXT in the SIS. For last item, had to print the Word file as a Postscript to force alignment of figure pieces with text, then distilled the Postscript to PDF/A. x There are summary files with names like hriv_3_4_epoxi_garrad.pdf. In at least some of these labels in some data sets, the Julian Date field is described as being in the form YYYYMMDD. This needs to be fixed if it applies to this data set. + Done. x The BODY_POSITIVE_POLE_CLOCK_ANGLE or whatever it is called, is stated to an unrealistic degree of precisicion for comets Garradd and ISON. It should certainly not be stated in these data to more accuracy than integer degrees. But in the document directory the table that lists geometry gives the same clock angle for this value as for the celestial north clock angle. If the value is not applicable, or otherwise unknown/unknowable, then the appropriate constant needs to be defined and used. + Done. BODY_POSITIVE_POLE_CLOCK_ANGLE is not really known for comet Garradd and ISON. Project revised data labels and geometry tables to use an appropriate value unknown. x In places that describe the file naming convention, there needs to be a clear indication of which time (beginning, middle, end) is used for creating the file name. + Not applicable. Mid-obs is used in the filenames and for grouping products into DOY directories, and this is already called out in the EPOXI SIS and dataset.cat files! x Please add a document equivalent to the "observing log" files found in other DI/EPOXI data sets listing comet centroids, image quality, known anomalies, and so on. + Done. Project provided a table of measured centroid. "Observing logs" were not prepared by the project because these obs were not from an actual flyby. CALIB/ ====== x In lindn/hriir_100928_1_1.lbl: AXIS_NAME = ("LINE_SAMPLES", "LINES", "PER_PIXEL_LINEARITY_COEFFS") is legal, but "SAMPLE" and "LINE" (singular) are much more common. + Done. DATA/ ===== x Some files, for example, 086/hi12032617_4000077_017.fit, appear to be missing data in a strip in one corner. This needs to be investigated, and either corrected or explained. It affects both raw and calibrated data, but there are more affected files in the calibrated data (because the calibration process propagates the bad data). + Done. The Data Coverage and Quality section of dataset.cat in all raw and calibrated HRII datasets already states that striping is due to missing pixels which are identified in the image quality map extension (FLAG). However, B.Carcich confirmed these area are indeed missing pixels, as noted in the FLAGS extension; it so happens that those pixels are in the last frame of an ExpID, which is used as a dark file, and so it contaminates the calibrated observations of the same ExpID. No action necessary on data files. Added note in calibrated HRII Garradd dataset about missing pixels in a frame used as a dark will replicate that effect in calibrated obs. Also added a note in the EPOXI Cal Pipeline Summary doc. x The BODY_POSITIVE_POLE_CLOCK_ANGLE or whatever it is called, is stated to an unrealistic degree of precisicion for comets Garradd and ISON. It should certainly not be stated in these data to more accuracy than integer degrees. But in the document directory the table that lists geometry gives the same clock angle for this value as for the celestial north clock angle. If the value is not applicable, or otherwise unknown/unknowable, then the appropriate constant needs to be defined and used. + Done. BODY_POSITIVE_POLE_CLOCK_ANGLE is not really known for comet Garradd and ISON. Project revised data labels and geometry tables to use an appropriate value unknown. Additional ========== ! If possible, please add some sort of browse facility to help users locate data of interest more efficiently. + Declined. Resources are limited, and project believes galleries adds very little benefit when viewing geometry does not vary much and is required for understanding these data.
