Downloading LWS Interactive Analysis (LIA) Version 8.1 patch

---

Major improvements with respect to previous version of LIA include:

• FP_PROC : Now using the liac file for determining the darks measured during the observation. The OLP 8 lsca file has the fixed dark values because we ALWAYS subtract fixed darks for ALL FP observations. User not allowed to exceed the measured dark or to go below the fixed dark, if it is less than the measured dark.
• INSPECT_RASTER : Bug fix to return RA, DEC and RP arrays rather than scalars
• DEFRINGE : This tool is written for interactive defringing of LWS data (L01, L03 and L04).

• The illuminator calibration file lcir.fits has been replaced in order to be compatible with OLP 8. The version in LIA 8.0 was appropriate for OLP 7 only.

UNIX and IDL 5.03 or higher.

ISAP version 2.0 should be installed on your computer, which contains the OLP 8 calibration files for the LWS.

LIA version 8.0 should be installed on your computer, which contains the full LIA 8.0 library.
