[IRC imaging toolkit version 20091022] In the new version, the following two points have been revised. (1) N2, N3, and N4 flat data have been updated. The systematic global shallow slope over the NIR array seen in the previous flats has been corrected for in the new flat data. (2) The WCS fits headers for MIR-L data have been corrected and they now give the correct WCS information from the AOCS. Note that they still have uncertainties inherited from the AOCS. To install the package, follow the instruction in Data Users Manual. Note that this distribution is a FULL package. Please delete or rename the previous version files before the install. === [2009/12/03]
