DECam Logbook Training V0.9HTD April 27, 2012

Logbooks

• Science uses Logbooks – To Record details of experiments, observations, results and

diagnostics, analysis and conclusions

• Science also use Logbooks for operations & status reports– The purpose is to maintain an accurate history so that we can

understand 1) that we did or found something, 2) what happened when we did it (observation), and 3) what we think

– Logbook also provides status information

• Detailed and accurate information is valuable to Operators and to Experts– It’s easy to forget details with time

– It’s easy to misunderstand verbal reports with distance

– Both distance and time are key factors DECam has to overcome. 2

Viewing the CTIO Logbook

• CTIO uses an electronic logbook for DECam – It’s located on a

computer and accessible by means of a web interface.

– http://system1.ctio.noao.edu:8080/ECL/decam/E/index

– Tools are available for searching, viewing, and putting information into the logbooks.

Logbook Entries

7

• Logbook Entries– Human-typed (you

wrote something) onto the page or into a form

– Computer-generated. E.g. alarms, exposures

• We’ll show you how to put them in.

Information is included as an “Entry”.Entries at the top of the page arethe most recent.

• To put an entry into the logbook you need to login. Click “login”

• Say how to login

• After login you will see additional info.

• “New Entry” is the one we want

• You select the Form & Category (same as before)

• For “default” you see the page already shown (left).

• Note: see Utility Checklist.

When to Use the Logbook

• As directed for routine activities– Example: Utility Checklist

• When we do something or observed something non-routine– Performed an unusual procedure. Example: “We installed the

filter changer into the barrel.”– Performed a rare maintenance operation. Example: “We

replaced the O2 sensor in the Coude Room.” Or “I discovered a suspected loose wire on O2 sensor in the Coude Room.”

– When something routine doesn’t work as expected. Example: “The shutter seems stuck. Here is the SISPI text dump.”

– Or to report a problem with documentation: “That’s not right!”.

• The logbook only helps when we use it. 14

Summary

• The purpose of the logbook is to maintain an accurate history so that we can understand 1) that one of us did something, 2) what it was we were trying to do, and 3) what happened when we did it

• Logbook also provides status information.

• We use it as directed by routine procedure• Whenever we do or observe something out-of-routine

• The goal is higher operational efficiency.• This training has shown you how to use the logbook.
