DATA TOOLS
—Zoom box Changes cursor zoom icon. Click and drag cursor over desired area of image. Make a new window, with aspect ratio of the click&drag and image 2x zoomed, meaning every pixel twice as big as in original image.
—Slice
Make slice cursor (knife?). Click and drag cursor to define slice line on image. Popup window shows graph of brightness (in counts) vs displacement along the slice line in pixels. Use pythagorean theorem to define displacement along the slice in pixels. Beginning of slice and end of slice define the x-axis of the graph in popup window. Click or click&drag along graph line makes a box on the graph line AND a red box moves along the slice line in the image corresponding to the box on the graph line. Crosshair cursor. At bottom of Popup "Slice" box the Distance value and Counts value is displayed, corresponding to position of the crosshair cursor. Title of popup window: "Slice"
When Popup Window is active, new menus are: File (has Open, Save As, Print, Close),
Options (Axis Setup, Style) – Axis Setup brings up a dialog box named "Axes Setup" that has Plot Title (name of image) and 3 columns – first column name of value; 2nd column is x-axis; 3rd column is y-axis. boxes to enter values: 1st column names of values are Label, Min (* for default), Max (* for default), Tick Marks (check box), Tick Spacing, Grid (check box). Style brings up dialog box with
Connect points [check box]
Plot Points [check box] with Radio button options: Cross and Circle
OK and Cancel
–Image Info (header) Display image header, non-editable
—Sky … (statistics)
On selection of Sky, 1st comes up a dialog box with Sliding Window Width [not sure what this is!!] and check box "Entire Image"; OK and cancel.
If check box is unchecked, user clicks&drags to define area of interest on image. Area indicated by red or pink rectangle (edge line only) Compute and display in Results popup window: Image/Filename; defined rectangle (coordinates of lower left corner and height and width of rectangle in pixels)
–Sky value (median brightness within defined area)
–Standard deviation
– –Mean
–Minimum brightness value and coordinates of pixel with minimum value
–Maximum brightness value and coordinates or pixel with maximum value (most common pixel – maximum of histogram).
When Results window is active, there is "Edit" menu with options: Copy, Erase Last, and Erase All
—Axes …[Maybe make new name, e.g "Centroid"] On selection of Axes, 1st comes up a dialog box with Check box "Entire Image"; OK and cancel. If check box is unchecked, user clicks&drags to define area of interest on image. Area indicated by red or pink rectangle (edge line only) Function:
Finds the center of a distribution of light, or center an extended object. Weighted average position of the extended object. Compute and display in Results popup window: Image/Filename; defined rectangle (coordinates of lower left corner and height and width of rectangle in pixels) Center: (coordinates of computed center of extended object(s))
Major axis and Minor axis of centroid.
When Results window is active, there is "Edit" menu with options: Copy, Erase Last, and Erase All
—Find …
On selection of Find, 1st comes up a dialog box with Check box "Entire Image"; OK and cancel.
If check box is unchecked, user clicks&drags to define area of interest on image. Area indicated by red or pink rectangle (edge line only) Radio buttons to choose one of two options: (1) "Perform Sky" in which case additional text says "Find Stars with pixel brightness above:" followed by second line "Sky +"
"* deviation" (1) "Threshold" in which case additional text says "Find Stars with pixel brightness above:" followed by second line Sliding Window Width: [Box to enter number (1-32767)]Function:
Finds all objects in the image or in the defined area if "Entire image" is unchecked. Process is gaussian fit and result is coordinates of all objects in the image or the defined area. Result popups up in Results Window as Find: [image/filename]; defined rectangle (coordinates of lower left corner and height and width of rectangle in pixels)
Threshold: [value]; Sky: [value] [table as follows] X Y FWHM Brightness [FWHM is full width half maximum]
When Results window is active, there is "Edit" menu with options: Copy, Erase Last, and Erase All
—Aperture …
1st comes up a dialog box with "Star Radius" [with box to enter value in pixels] "Sky Radius [with box to enter value in pixels]; OK and Cancel.
Cursor becomes bullseye.
Function:
User clicks on a star, it finds center of object (as in Find), and then adds count values of all pixels in the star radius disk. Then finds median value along the circle at the sky radius. Multiplies median value by the number of pixels in the star radius disk and then subtracts result from total count in star radius disk. Result popups up in Results Window as Aperture: [image/filename]; coordinates of star [x, y values]
Brightness: [counts value]; Sky: [value]
Star Radius [value]; Sky Radius: [value]
When Results window is active, there is "Edit" menu with options: Copy, Erase Last, and Erase All
—Auto Aperture
Operates like Aperture, but there is no 1st dialog box.
User clicks on a star. Program runs "Find" function (gaussian fit) to get coordinates of star and "centroid" (Axes) function and calculates 3 times the full width half max from centroid -and that’s Star Radius. For Sky Radius value is 6x full width half max. Then it runs Aperture function using those values for Star Radius and Sky Radius. Result popups up in Results Window as
Aperture: [image/filename]; coordinates of star [x, y values]
Brightness: [counts value]; Sky: [value]
Star Radius [value]; Sky Radius: [value]
When Results window is active, there is "Edit" menu with options: Copy, Erase Last, and Erase All
—Histogram … 1st Dialog box: Check box for "Entire Image". Check box for "Normalize"; OK and Cancel
Sliding Window Width…????
If check box is unchecked, user clicks&drags to define area of interest on image. Area indicated by red or pink rectangle (edge line only)
Function:
Make histogram graph with x-axis Brightness (in counts) and y-axis is "Frequency" (number of pixels with given x-axis value). Menus: File (has Open, Save As, Print, Close), Options (Axis Setup, Style) – Axis Setup brings up a dialog box named "Axes Setup" that has Plot Title (name of image) and 3 columns – first column name of value; 2nd column is x-axis; 3rd column is y-axis. boxes to enter values: 1st column names of values are Label, Min (* for default), Max (* for default), Tick Marks (check box), Tick Spacing, Grid (check box). Style brings up dialog box with Connect points [check box]; Plot Points [check box] with Radio button options: Cross and Circle; OK and Cancel
WINDOW (standard functionality)
HELP (help text, search, and navigation system)
ADDITIONAL FEATURES
For Open
ADD option for getting image from WWW.
Blink Comparator function — acts much like a slide show to compare images. User must be able to control speed of blink back and forth between two (or more) images.
RA-DEC – Celestial Coordinates to Pixel Coordinates transformation function:
If header information includes celestial coordinates of a particular pixel, then software can display in "Status Bar" where x, y pixel coordinates are displayed, the celestial coordinates (Right Ascension and Declination) as well.
