I would like captions (which will always be above the figure, table, etc) to be placed in the same vertical position on the page. I know I can do
\makeatletter
\setlength{\@fptop}{0.16\textheight minus 0.160\textheight}
\makeatother
which makes the vertical position 16% of the way down the text height. However, I am using twocolumn report document and when a figure is placed early in a chapter, the figure appears lower. I understand that this is because it is 16% of the textheight + chapter title area height.
How can I make such figures appear on the same vertical position as other figures?
I have a MWE which achieves the effect below, but requires me to manually determine the correct height of the minipage, and to use a separate environment from figure for figures appearing on the chapter page. Is there another way? Alternatively, if this way is the best, is there a way to refer to the "chapter title area height" so that if I change the way chapters are displayed the same effect is achieved?
(If a figure is too large on a `normal' page, I am not worried if it moves up.)
