The following automatic conversions were performed:

'_cell_measurement_temperature' value 'room temperature' was changed
to '295(2)' - the room/ambient temperature average [293;298] in
Kelvins(K) was taken.

The following automatic conversions were performed:

'_cell_measurement_temperature' value 'room temperature' was changed
to '295(2)' - the room/ambient temperature average [293;298] in
Kelvins(K) was taken.

'_diffrn_ambient_temperature' value 'room
temperature' was changed to '295(2)' - the room/ambient temperature
average [293;298] in Kelvins(K) was taken.

'_symmetry_cell_setting'
value 'Monoclinic' changed to 'monoclinic' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 2F~o~Lp/[\s^2^(I~o~) +
(0.02I~o~)^2^]^1/2^' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w = 2F~o~Lp/[\s^2^(I~o~) + (0.02I~o~)^2^]^1/2^'.
