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.

'_refine_ls_weighting_scheme' value 'w = 2F~o~Lp/[\s(I~o~)^2^ +
(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(I~o~)^2^ + (0.02I~o~)^2^]^1/2^'.
