    News

    v3.3 (2017-03-20)
  • The default data path is /Volumes/DATA_DUPONT/RETROCAM/utYYMMD1_D2.
  • Open the data path(s) in a Finder window via the File--Show DataFolder menu.
  • Removed the "Cass. Encoder == fixed value" feature from the Preferences panel.
  • This feature allowed to enter the cassegrain rotator position manually to avoid erratic encoder readings.
  • Fixed a logfile permissions bug and made some other code improvements.
  • Interaction with the M2-GUI:
  • Read the FF-Lamp status and M2-Focus from the M2-GUI running on vinchuca (iMac on TO console).
    These are written to the FITS header (keywords: FFLAMPS, M2FOCUS).

    Data Acquisition

    Camera -- DataPaths -- Dither -- QuickLook Tool -- Macros

    Camera

    ExpTime: sets the exposure time (3..999 seconds)
    ReadMode: sets the readout mode
    {Double, Quadruple, Sextuple, Octuple, Single, Bias, Reset}
    ObjType: sets the object type
    {test, standard, astro, tflat, sky, dark, dflat}
    Filter: moves the filer wheel to the selected filter
    {dk, Yc, Jo, Hc}
    Go: starts a loop sequence of Loops exposures
    Loops: number of exposures per sequence
    Object: OBJECT value in the FITS header
    Filename: name of the next FITS file
    File: macro scripts filename
    Dither: opens the dither-macro dialog
    Execute: executes the macro-script
    Pause: pauses the current macro-script (after the current command)
    Abort: aborts the current macro-script (after the current command)
    Disk(s): disk status

    Data Path(s)

    The FITS files will be written to both paths simultaneously.

    Dither Macros

    This dialog creates standard dither macro-scripts.
    Step: step size [arcsec] between exposure loops
    Pattern:
    {None, Dice-5, Rot-5, Square-9, Rot-9, Random-11}
    Guider:
    {None, Auto, Manual}


    QuickLook Tool

    Magnifier (top right)
    Can be moved by holding down the left mouse button, or with the cursor keys (up/down/left/right arrows).
    Pixel
    The current cursor pixel coordinate (center of the aperture and magnifier) and pixel value at the cursor position.
    Min/Max
    Minimum and maxium pixel value within the aperture.
    Ave/Sig
    Average and standard deviation within the aperture.
    FWHM/Flux
    Press the key while centered on a star to calculate an estimated FWHM and flux.
    Magnification
    Magnification factor of the Magnifier window.
    Radius
    Sets the radius for the aperture statistics (MinMax, AveSig above).


    Telescope Control

    TeleGUI -- SkyMap -- Airmass -- ObjectList

    TeleGUI

    Get: Reads the telescope coordinates (alpha, delta, equinox) and focus from the TCS (telescope control system).
    Note: It is recommended to press the Get button before starting a macro to ensure proper telescope pointing. This also updates the focus value that is written to the FITS header.
    Send: Sends the coordinates in the Alpha and Delta windows to the TCS.
    NE,N,NW,E,W,SE,S,SW: Moves the offsets from the dx and dy windows.
    0,0: Moves the negative offset from the S(dx),S(dy) windows.
    Zero: Resets the offset-sums in the S(dx),S(dy) windows to zero.

    SkyMap

    Displays the current view (red square) of the RetroCam array.

    Airmass

    Shows a graph of the change in airmass at the current telescope position.

    Object List

    The object lists a ASCII files, formatted as one object per line; each data field is seprarated by a '|' (pipe) character:

    Name | 10:50:10.0 | -12:00:15.0 | 2000.0 | Comment
    
    Edit: opens a dialog that allows to change the properties of the selected object.
    Add: opens a dialog that allows to add an object to the list.
    If the coordinates (alpha, delta, equinox) are left empty they will default to the current TeleGUI coordinates.
    Remove: removes the selected object from the list.
    PreView: sets the coordinates in the TeleGUI
    and Airmass window to the selected object (coordinates are not sent to the TCS).
    setObject: Sends the coordinates of the selected object to the TCS.
    If the equinox of the list object is different from the equinox of the TeleGUI (TCS), then the coordinates are precessed to the TCS equinox before they are sent.
