WIRCam webpages have been updated with recent additions and improvements to the instrument as well as the processing pipeline, `I`iwi. Documentation regarding the current version of the production pipeline, `I`iwi ver 2.2 have also been updated and are available online.

The `I`iwi Documentation and recipes can now be found on the WIRCam web page. It describes most steps of version 1 of the pipeline.

Preprocessing of all past semesters data with the first stable release of the IDL Interpretor of the WIRCam images (`I`iwi) has started. More details about the `I`iwi will be posted on the main WIRCam page soon. Priority is to preprocess all programs of the 06B and 07A semesters first then move back to the older data.

As expected, the new hardware setup for WIRCam is producing very encouraging results. No apparent positive crosstalk can be seen and the negative crosstalk has disappeared entirely. The edge crosstalk is still present but its effects are not as strong as that of negative crosstalk and we cannot seem to reproduce its effects in the lab. So more work will be required to understand it.

Meanwhile, shallow stacks (1000 sec) have shown that the technique to remove edge crosstalk effects in software is effective with very little residuals. Deep stacks will be produced to see what the residual levels are for fields with long integration time.

Good news, the non-linearity characterization for data taken since semesters 06B has now been finalized. The correction has also been included in the pipeline. At high flux, the linearization process increases the flux by up to 10%. We are in the process of reprocessing the standard stars measurements to see what will be the impact on zero-points.

Data preprocessing of the 06B/07A data will start as soon as some last astrometry bugs get fixed. Distribution of preprocessed data should happen before the end of August.

A hardware solution has been found and implemented to entirely get rid of the worst crosstalk: the "negative" crosstalk (one of three different crosstalks affecting WIRCam images). The coming July 6-16 observing run will be the first with the "new" instrument.

The processing pipeline, Iiwi - version 1, is a few weeks from being completed. The final touches to correct for the non-linearity are still being implemented. Work has focussed lately on a good crosstalk correction, a better star masking technique for the sky construction, automatic handling of dark/flats processing as well as a more robust astrometry determination.

Semesters 06B and 07A data will start being processed by the end of July and distribution should start before the end of August 2007. Documentation will then be added on this web page with this first Iiwi release.
