FURTHER CONFIGURATION

If not already set using the -ut command line option, and if you are using a loop type where it is necessary to build the filename using the UT date (i.e. all loop options except file) the UT date of the observation run can be set via the relevant text entry box in the middle of the main window. NOTE Doing so will run the instrument setup routine again which will override some environment options such as ORAC_DATA_IN and ORAC_DATA_OUT.

If ORAC-DR is being run in post-observation mode, the default data detection loop is list. Other loop options can be selected using the series of checkboxes along the bottom of the main window. The available options are

list

The pipeline will stop once the observations in the list have been reduced.

wait

Waits for data to appear before timing out. Data is reduced and the pipeline waits for the next file.

inf

Do not wait for data. Simply reduce data starting with observation specified by from and continuing until no more files are present. This is the fastest way of reducing data offline.

flag

Waits for completion files to appear (flags) before processing the data. Data is reduced and the pipeline waits for more data by checking the presence of a flag.

file

Works much like the list loop option except that looping is carried out over a list of arbitrarily named files. When the file loop option is selected the Select Files button will be enabled allowing you to generate this list. NOTE As well as having arbitrary filenames, files can be added in arbitrary order, this allows you to reduces (for instance) all the calibration frames for a night first, followed by the actual observations.

There are, in addition, two other options which affect the looping scheme, these being batch and skip.

batch

Run in batch mode. Precalculate groups before processing data. `wait' loop mode should not be used with this option. NOTE only SCUBA recipes support this option.

skip

Allow the data detection loop to skip missing observations. Default is to stop the loop when an expected file can not be found.

See the DataLoops documentation for more information on looping schemes.
