| | 8 | After a couple of false starts and delays, we have finally updated the |
| | 9 | operational IPP to the latest version. |
| | 10 | |
| | 11 | The regular processing is now being performed with the IPP tag |
| | 12 | ipp-20101029 (the Black Friday tag...). This can be found in our svn |
| | 13 | tree at: |
| | 14 | |
| | 15 | https://svn.pan-starrs.ifa.hawaii.edu/repo/ipp/tags/ipp-20101029 |
| | 16 | |
| | 17 | This update incorporates a number of changes that have been in the |
| | 18 | works and in testing since the meeting at Belfast. Here is a summary |
| | 19 | of the most important changes and improvements: |
| | 20 | |
| | 21 | * new output formats : PS1_V3 and PS1_DV2, with a number of new fields. see: |
| | 22 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/CMF_PS1_V3 |
| | 23 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/CMF_PS1_DV2 |
| | 24 | |
| | 25 | * the Star likelihood measurement and the Cosmic Ray detection are |
| | 26 | improved, see the discussion at: |
| | 27 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/StarGalaxySeparation |
| | 28 | |
| | 29 | * Cosmic Rays are now masked in the chip-stage output images |
| | 30 | |
| | 31 | * Some improvements to both the DUAL and SINGLE convolution analysis, |
| | 32 | discussed at the following link (more discussion to be added soon): |
| | 33 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ppSubModifications_201009 |
| | 34 | |
| | 35 | * Stack masking now includes information about the cause of masked |
| | 36 | pixels, as well as information about suspicious pixels. see: |
| | 37 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/Stack |
| | 38 | |
| | 39 | * Fixes to the bright star masking: The size of the bright star |
| | 40 | circles was OK for very bright stars (-23 inst mags), but too small |
| | 41 | for stars at or just beyond the saturation limit. This is now fixed. |
| | 42 | Also, the w-band images used too small of a zero point for the over |
| | 43 | all scaling. |
| | 44 | |
| | 45 | * STACK-STACK processing now uses SINGLE convolution of the template |
| | 46 | instead of DUAL convolution |
| | 47 | |
| | 48 | * addressed a couple of low-level bugs that caused errors in the |
| | 49 | calculation of centroids or screwed up the peak positions in some |
| | 50 | chips |
| | 51 | |
| | 52 | * for faint sources, where we do not perform a full non-linear fit for |
| | 53 | the position, we are now reporting the position and position errors |
| | 54 | based on the centroids rather than on the peak in the detection image. |
| | 55 | With the fix above, this gives much more reliable values for the |
| | 56 | position and errors on these faint sources. |
| | 57 | |
| | 58 | * for forced photometry, we are now keeping the supplied position (the |
| | 59 | code had been letting the position be reset by the pixel analysis, |
| | 60 | which is definitely wrong). |
| | 61 | |
| | 62 | This release includes some fixes to psphotStack, which is used for the |
| | 63 | 'static sky / deep stack' photometry, but there are a few outstanding |
| | 64 | concerns that have not yet been addressed. This release also does not |
| | 65 | address the STS desire for forced photometry in the diff images of the |
| | 66 | input image sources. |
| | 67 | |
| | 68 | Also note that MOPS will continue to receive the old format tables |
| | 69 | until they are ready; the detections are being generated at the diff |
| | 70 | stage with the new format (PS1_DV2), but the publication process is |
| | 71 | producing the old format. |
| | 72 | |
| | 73 | Finally, this is NOT the final IPP version release before the Great |
| | 74 | Reprocessing. Aside from the issues listed above, there are some |
| | 75 | other things to be addressed. We will be producing sample |
| | 76 | re-processing of MD04 and SAS data, among others, for feedback. I |
| | 77 | suspect it will be 2 - 3 weeks before everything else that needs to be |
| | 78 | addressed before the Great Reprocessing can be addressed. |
