| | 36 | With these parameters 961 trial galaxy fits were performed for each object selected for fitting. The average processing time for each warp was |
| | 37 | 960 seconds. This is prohibitively expensive for the 3PI survey. In fact we stopped the test after processing only 20% of the skycells because it |
| | 38 | was taking so long. We believe that this limited test provides the good enough statistics for analysis. |

| | 42 | The latest SAS stacks (label SAS.20130620) were processed through the staticsky and skycal stages of the IPP using the candidate PV2 version of |
| | 43 | psphot (tag ipp-20140114). |

| | 45 | The code is essentially the same as that used for SAS_32 except that the selection of objects for extended model fitting was relaxed. In particular |
| | 46 | the previous requirement that the object be "extended" (EXTNSIGMA > 3) is not used. Instead magnitude cuts were used.The cuts chosed are 21.5 in g, r, and i. 20.5 in z and 19.5 in y band. Note that these cuts are per object. If the object's magnitude was less |
| | 47 | than the cut for any band, fits were performed in all bands. |
