Quality assessment details (.qadet) FileDescription

This ASCII filecontains the values for each metric calculated during the qualityassessment. The calculations are based on a number of attributes(i.e. phase jitter) and for each attribute the caulcated value and thepercentile are given. Each line corresponds to one band (wide-bandchannel, summed spectrometer or individual spectrometer channels).The following gives an example of a line from a KI .qadet file:

QADET ../../../2004/08:44:39  8.744241  HDC27406  1.2   KI_K1K2  WB  4  6  2  0.44 18  316.87  18  0.66  75  0.00  100  0.45  17  0.01  90  330.11  21  0.69  70 0.34  100  74.99  52  0.39  32  0.04  97

The line consistsof a number of space-delimited fields. The meanings of these fieldsare summarized in the table below. Each line corresponds to a blockaverage of data (typically from 5 to 25 seconds of fringe data, notnecessarily contiguous). All entries, including time and delay lineposition, are mean values for the block. A value of NULL indicatesthat the quantity was not calculated. See the QA overview for details on the QAcalculations. A # as the leading character indicates a comment.

field#	content	comments
1	QADET	a literal string; each line starts with QADET.
2	date	UTC date of the observation (../../../yyyy/hh:mm:ss)
3	time	Mean observation time (decimal UTC hours)
4	target	Target designation (ASCII string)
5	context version	CVS version of context file
6	baseline	Baseline name
7	Band ID	ID for this band. Allowed values are WB, spec and integers for the individual spectrometerchannels
8	Num. record attributes	The number of attributes in the record score.
9	Num. scan attributes	The number of attributes in the scan score.
10	Num. night attributes	The number of attributes in the nightly score.
10	Record att. 1 value	1st record attribute value.
11	Record att. 1 score	1st record attribute percentile score.
...	value, percentile	For each record, scan, and night attribute a pair ofvalue/percentile numbers is given.
