Observer2/AstroChair setup and Data Quality Operations

Guider Plots

Somewhat outdated - Guider plots were useful during SV. We no longer experience "Guider Oscillations" or "Guider Jumps"
In the upper left is a browser showing the display of the Guider Plot. Just below that is the xterm that controls it. This is a simple Python tool that will generate a plot when you demand it. Typical usage occurs if we see that images are elliptically-shaped from Quick Reduce and check to see if there are "Guider Oscillations". Instructions for setup and usage are available at Guider Plot Instruction

Save plots to the desktop and put them in the ELog. Delete them from the desktop once they are put into the ELog.

RASICAM Display

Clockwise from the Guider Display we next see the browser with the Rasicam Display and tabs for several other
environmental monitors. Set them up and learn to read them.

Quick Reduce Display

Clockwise from the RASICAM display is the Observing History window from Quick Reduce. We pay close attention to that, monitoring the seeing and ellipticity reported by QR. Login and Instructions are available at

At the end of the evening or night, use "import" to capture the Quick Reduce plots, save them to the a directory and copy them from there into the Elog, tagging them as "summary". Do that before the Night Summary is made and the plots will then appear in the Night Summary.

Navigation Plots

Clockwise from the Quick Reduce Display is the Navigation Display.
Instructions for setup and usage are available at Navigation Plot Instruction

Elog

Continuing clockwise we encounter the ELog.

Kentools

Continuing clockwise from the Elog we have the kentools xterm ( hint: "inv; load; seeingall"), and display. Kentools provides user-driven utility tools for image analysis. We use kentools kentools to monitor seeing (psf), for offset centering information, and for ds9 display, which is automatic.

After taking the domeflats run "flatCheck". Save the diagnostic plot that pops up (e.g., using xv and grab window). Attach this plot to the Elog report at the end of the night.

Other Displays

If the AstroChair is maintaining the nights sum, then a vi window or emacs window is usefully
in this display.
