Version History

v2.1, v2.0
v1.5 and older

v2.1.1 (2018-10-18)
  • Added the missing site informaton (latitude, longitude, altitude).
    • This also fixes the "AIRMASS" and "ST" records in the FITS header.
    The site information was correct upto v2.0.2 but got "lost" in v2.1 (2018-05-25).
    v2.1 (2018-05-24)
  • Modified the "subraster" record of the FITS header to indicate the actual subraster geometry even if the full ('0' padded) frame is saved.
    • SUBRASTR='[x1:x2,y1:y2]'
  • "Trim bias section from loaded FITS files" option on the Preferences/QuickLook pane.
    • This allows to display the bias sections (overscan and biaslines) in the QuickLookTool for FITS files loaded from disk (not for data directly read from the array).

    v2.0.2 (2017-05-15)
  • Changed the permissions of the logfile to read/write all.
    • This allows different observer accounts to append to a pre-existing logfile.
    v2.0.1 (2017-03-03)
  • Changed the file permissions of saved subrasters to read/write all.
    • This allows different observer accounts to overwrite pre-existing subraster definition files.
    All accounts write to the same 'Subrasters' directory in /Users/Shared/Library/Applictaion Support/Echelle/
    v2.0 (2017-02-28)
  • Installed the official release version of the new Echelle GUI.

    • v2-beta-0039 (2017-01-17)
  • Send email when the dewar temperature gets too high.
    • Gabriel Ferrero reports on 2017-01-14:
    ... during last two nights I used the new Echelle-GUI all the time. I couldn't detect any issues. As far as I could see the headers were correct.

    v2-beta-0038 (2017-01-09)
  • Ported the Echelle (ccdgui, X11) to macOS/Cocoa.

  • Added FITS records:
    • FFLAMPS : flat field lamps from the M2-GUI.
    M2FOCUS : M2 focus from the M2-GUI.
    DATASEC, TRIMSEC : standard NOAO keywords.
  • Changed FITS records: --- please let me know if this creates a problem ---
    • SITELONG = -70.70384 (was -70.70387)
    SCALE = 0.259 (was 0.260, see note A on the duPont telescope website).
  • Removed FITS records: --- please let me know if this creates a problem ---
    • APERTURE, FILTER, ASECS, DSECS, VGAUGE, IGAUGE
    These keywords do not have any meaning in the context of the Echelle instrument and were only in the FITS header because the ccdgui is shared between multiple instruments.

  • Default data path is /Volumes/DATA_DUPONT/ECHELLE/utYYMMD1_D2.
    • Open the data path(s) in a Finder window via the File--Show DataFolder menu.

  • 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).

  • Interaction with the TeleGUI:
  • Please offset the M2-focus via the TeleGUI:
  • The Object and Comment edit fields on the GUI are automatically filled with the values in the ObjectList of the TeleGUI when the SendToTCS button is pressed.
  • The SkyMap displays the position of each exposure onto the SkyMap as a green rectangle the size of the CCD array.
    • These features require TeleGUI-v1.8.1 or newer.

    v1.5 and older
