TMPL1PHOT (aka DISA_IRASPH) ========= > = comments by SAM > N.B. DISA_0002 is the ID used for the review. The VOLUME_ID for the archive is DISA_0004. For other DI volume ids, see http://pdssbn.astro.umd.edu/internal/doc/DI_stuff/di_volume_ids.html The AO resolution question noted for DISA_0001 has a critical bearing on this data set. These data cannot be accepted until that answer is known and the impact on this data set can be determined. If the answer is simple and clear, there is no need for additional review on this point. > Per Russell Walker, we must include the effective resolution tables (also known as the beamsize reports) in the AO FITS image archive. The IPAC software that Walker used to reconstruct the AO images required a default pixel size for processing. Walker selected a size of 15 arcseconds/pixel because this was the best possible choice for these data. However, this pixel size is not necessarily the effective resolution across the entire image. Therefore, as each image was reprocessed, the software generated a table of that gives the actual, effective resolution for selected pixels in across the image. Per Walker, these tables "are the closest one can get to an estimate of the actual beam size and how it varies with position within the image". Therefore, the effective resolution/beamsize tables were included in the DISA_IRASIM data set. The documentation contains a recipe for further processing. Sykes questions the validity of the IRAS re-calibration procedure proposed. The potentially controversial nature of the described procedure needs to be clearly stated, at the least. Preferably, the controversy should be solved and the ultimate solution documented. > Lisse and Skyes discussed this issue after Lisse found more evidence that the proposed IRAS re-calibration procedure is valid. However, it was decided that the version of the photometry tables that was reviewd should be archived. This version did not have the IRAS re-calibration procedure applied. Also, the photometry documentation was modified to include the additional evidence for the validity of the IRAS re-calibration procedure. The recipe for using the process was not removed from the documentation. In the explanatory document, amend the Figure 2 caption to indicate more clearly that the data plotted have been further processed from the data obtained from Russ Walker. > Amended Add explicit reference to the "IRAS Explanatory Supplement". (Note that this is available as HTML on line from www.ipac.caltech.edu. > Added Add horizontal bars in Figure 2 showing filter FWHM. > Added Page 2: change reference to "fields of view of bandpasses" to "fields of view of detectors". > Changed Expand on the discussion of the technique used to subtract background from the various images. Mark notes there might be additional survey data of the same area (in ISSA) without the comet in it that might be useful for comparison. > Expanded with additional information from Lisse
