3     * Subroutine cnoise.f!DA COMMENTARE!???
4     *
5     * uses adc(nviews,nva1_view,nstrips_va1) and
6     * pedestal(nviews,nva1_view,nstrips_va1) variables to compute common noise,
7     * and fills cn(nviews,nva1_view) variable. in the computation only
8     * not-bad and not-signal-affected strips are used
9     * (bad(nviews,nva1_view,nstrips_va1) and
10     * clstr(nviews,nva1_view,nstrips_va1) flags)
11     *
12     * needs:
13     * - ./common_calib.f
14     *
15     * to be called inside ./cncomp.f
