This is an enlarged image which can be seen more clearly than the Thumbnail or Detailed Aspects can offer. The initial image when received, is displayed at a 1:1 ratio. If the image is larger than the client area, the display starts at the center of the image. The cursor location on this aspect will relate to the Pixel Matrix and Line Profiles when toggled.
Fine Movement on the Image
...
Sometimes you need to make adjustments to the image to suit your purposes. Some of these adjustments may be as simple as zooming in or out and some may be as complex as changing the color scale or the way the pixels are scaled on the image. All of the tools you need are located directly above the Thumbnail and Detailed Aspects. There are also a set of functions that can be launched via this menu bar. These functions are instrument dependent. The menu below is for LMI.
Color
This provides a drop-down menu of available color maps that can be used as well as an invert-color option. The list and the RGB values were copied from IDL. The default is linear grey scale.
Image Zoom
The 4 controls with the magnifying glass allow you to control the ratio of the image to what is displayed. The magnifying glass with a plus or minus sign will let you zoom in or out of the image respectively. The third magnifying glass from the left will reset the ratio back to 1:1 and the last magnifying glass will fit the image to the client area.
...
Adjusts the brightness of the image. The left arrow decreases the brightness and the right arrow increases the brightness.
Scale
Scale drop-down allows the user the image transform function. The upper part choses the function and the lower part the limits. The default is ZScale-Linear where zscale is based on the IRAF algorithm. "User Defined" brings up a dialog box with a display of the intensity histogram where the user can set the limits.TODO
Color

Define ROI
A way to define different types of regions of interest.
Move Target
A way to do collimation and pointing offsets from the imager.
Focus (LMI)
Allows initiating the focus script from the imager. The drop-down has 2 items; one for setting the parameters and the other one for initiating the command:
Selecting "Focus Parameters" brings up a dialog box which is pre-filled with the default values read from the config file:
The second item on the drop-down, "Mark & Initiate Focus Run", allows selection of a target star by clicking on it. The x & y coordinate of the star is included in the inplacefocus command sent to LOIS.
For more information on the parameters and the inplacefocus script, you can refer to Autofocus Script (LMI) for LOIS.
