3D slice of the z=2 universe: Reduced data


Characterisation of Reduced frames

The tables below characterise the reduced frames. The purpose of the tables is to help identify which frames should be grouped up for the optimal combination, and with which input parameters. Each table lists frames taken with a given filter, centred on a given pointing (plus/minus some small dither offset), of a given field. Field 0010 is our primary field, and the goal is to obtain a complete 3 by 2 pointings mosaic (a total of six pointings) of this field. For each allocated night where part of the night cannot be used for this primary field, one of the alternate fields will be observed instead. Each row of each table fully characterises a frame.

Date: Frame was obtained on the night following this date
Raw_file: Name assigned raw data by the data acquisition tool
Reduced: Name of reduced (Bias, Dark, Flat) data frame
Exp: Exposure time in seconds
Airm: Airmass given in image header
See: FWHM of stellar images measured on the frame (mean of x and y)
Sky: Sky level in counts
rms: std dev of sky counts measured in several object free regions
x-off: Dither offset in x direction (in pixels)
y-off: Dither offset in y direction (in pixels)
m-off: Magnitude zeropoint offset from a given arbitrarily chosen frame

Sattellite track across image. Must be masked
Image is "double" - tracking close to zenith?
