	* src/absorption.cc (calc_gamma_and_deltaf_artscat4):
	Set in effect catch for broad_spec_vmr_sum==0 with additional catch of
	vmr_self==0 simultaneously (that can happen now that we apply
	zero-padding in AtmFieldsCalc when p_grid exceeds range of all gas
	profiles of the atm scenario).
	!!! In the latter case, xsec will be 0 - needs to be confirmed whether
	this is consistent with the general use of LUT (in general,
	abscoefs=xsec*vmr are 0 for vmr=0, but xsec are defined to be
	independent of vmr. that is, with the current solution we could get
	problems when trying to use this LUT for non-zero vmr) !!!

	* src/m_abs_lookup.cc (abs_lookupInit):
	Proper initialization of (empty) abs_lookup.

	* src/workspace.cc (abs_lookup):
	Corrected reference to corresponding section in AUG.
