Flip FITS Images

If not checked, FITS images are displayed in the conventional way with row number increasing upward.

If checked, FITS images are displayed in the unconventional way with row number increasing downward. See FITS Image Orientation.

Transfer Function Log Y Axis

Plots the logarithm of frequency on the Y axis of the histogram in the Transfer Function Properties dialog. Check this item to enhance the appearance of low frequencies when the histogram sample includes a small number of contaminating high pixels such as stars.

List non-existent images

With this item checked, Mira announces every image in a File List that could not be found. Typically, this is a big waste of your time, so leave it unchecked.

Close command dialogs

Controls whether the modeless command dialogs automatically close when you click [Process]. Modeless dialogs are dialog windows that let you work outside them while they are open.

Use Save Path as Open Path

Copies the last saved path into the default Open path. Usually, you would leave this item checked.

Use MTI interface

Activates the Multi-Tab Interface which displays a row of tabs for all the currently open view windows.

Hold 1-D plot draw on resize

Enables redrawing of the Plot Window while being resized. For most plots this is desirable. However, you may make a plot that has so many points in so many series that Windows cannot keep up with re-drawing it during a plot Window resize. In that case you can get back your user interface by checking this item. With the Delay flag enabled, Mira holds the redrawing operation until after you have finished adjusting the size of the window.

Hold 3-D plot draw on resize

Enables redrawing of the3-D Plot Window while being resized. This helps prevent loss of system performance when you resize or move a window containing a large or complicated 3-D plot.

Prompt to close Reports

Check this box to force Mira to prompt you to confirm that you want to close aReport window. The prompt also gives you a chance to save the report contents.

Prompt to close Plots

Check this box to force Mira to prompt you to confirm that you want to close a Plot window.

Prompt to close 3D Plots

Check this box to force Mira to prompt you to confirm that you want to close a 3-D Plot window.

Image Information

This list box lets you set the default format for image information that is displayed by clicking on an Image Toolbar. Usually you would set this to FITS Format so that luminance images show information in the FITS Header dialog. RGB images have no FITS format support, so information about RGB image is always shown in the Image Info dialog anyway.

Expanding Tooltip Offset

Sets the vertical offset, in screen pixels, of the expanding Tooltip. The expanding Tooltip has a small triangle that permits you to view more information by clicking on the tip text. If you have trouble moving from the control onto the text without crossing another control in between (which closes the text), reduce the offset to move the pop-up tip text upward toward the control. After clicking Apply or Save, you will need to re-open a particular window to see the change take effect.

3-D Plot Window

Selects the initial size of 3-D Plot windows. Select "Current" to set the default size to the size of the current 3-D Plot Window on top of the window stack.

Table Cell Font

Sets font properties used in the cells of data tables, such as in the Plot Series Data dialog or the Aperture Photometry calibration dialog.

Table Head Font

Sets font properties used in the column headings of data tables, such as in the Plot Series Data dialog or the Aperture Photometry calibration dialog.
