Version History

v2.1 (2018-05-10)

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).

v2.0.3 (2017-05-19)

Enforce unique filter/aperture names.

v2.0.2 (2017-03-21)

Changed the permissions of the logfile to read/write all.

This allows different observer accounts to append to a pre-existing logfile.

Fixed a bug in the routine that requests the password for enabling

the engineering mode (required to change the CCD voltages).

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/WFCCD/

v2.0 (2017-02-28)

Installed the official release version of the new WFCCD GUI.

v2-beta-0019 (2017-02-24)

Successfuly tested by Patrcio Pinto (Feb/27) -- Thanks!

v2-beta-0016 (2017-01-31)

Moves the wheels sequentially (internal interlock).

Changed the communication with the wheel controller.

v2-beta-0013 (2017-01-25)

Allow to change the wheels during exposure/readout.

Changed the communication with the wheel controller.

v2-beta-0012 (2017-01-24)

Ported the WFCCD (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)

Removed FITS records: --- please let me know if this creates a problem ---

ASECS, DSECS, VGAUGE, IGAUGE

These keywords do not have any meaning in the context of the WFCCD instrument and were only in the FITS header because the ccdgui is shared between multiple instruments.

Default data path is /Volumes/DATA_DUPONT/WFCCD/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.

v1.5 and older
