LARI Method

The LARI method is a powerful reduction technique for imaging data obtained with the ISOCAM and ISOPHOT cameras onboard the ISO satellite. It is based on a mathematical (but actually arising from simple semiconductor physics) model describing the signal generated by both celestial sources and cosmic ray hits as the contents of two charge reservoirs evolving with different efficiencies and time scales are released towards the detectors' contacts.

The method has been applied to a number of ISO extragalactic surveys in the ELAIS, HDFs, Lockman Hole and Marano fields. In particular, the ELAIS 15 Micron Final Analysis produced the largest single catalogue of extragalactic sources obtained to date from ISO data.

Papers dwelling on the technicalities of the method include:

Original method applied to 15 micron data : Lari et al. 2001, MNRAS, 325, 1173

Extended method applied to 90 micron data : Rodighiero et al. 2003, MNRAS, 343, 1155

Improved method applied to 15 micron data : Vaccari et al. 2005, MNRAS, 358, 397

LARI Package

The software implementing the LARI method has been assembled into a software package.
The package is briefly described in a Draft User's Manual.
IDL help info is available for individual routines.
