Gemini 2002A Execution Details

For each night scheduled for science (queue or classical) observing, the programs attempted are listed in the table below. 

The intent is to update the log after each night. At present, collection of this information is a manual process and it may not be possible to update it as frequently (e.g. updates only after every instrument block). As the data processing pipeline is also run manually, the data resulting from the observations will often not undergo the final quality assessment until after the (typically, 10-14 night) block assigned to that instrument has finished. Data packaging and distribution may take one to several weeks longer depending on the size of the dataset.

Jump directly to the nightly summary log for:

Not all of the night may available to science use as planned engineering/commissioning tests may also have been scheduled. The weather conditions show the range experienced (image quality at the specified wavelength has not been corrected to zenith). Summaries of the approved queue and classically scheduled programs are available together with their abstracts.


The columns in the table for Gemini North are:
Date: the calendar date of the observations.
Usable: the usable science time in hours (defined as nautical sunset to sunrise, but may be less due to scheduled engineering/commissioning tests).
Lost: time lost due to weather and/or technical problems.
Weather: a general summary of the weather conditions for the night in question.
Programs attempted: the Gemini reference numbers for programs (some of) whose observations were attempted.
