This recipe takes a night’s observations, and creates a text file containing a headed tabulation of parameters for each frame.

The parameters are: observation number, object name, observation type, UT start time, exposure time, number of coadds, read mode and speed, filter, start airmass, frame dimensions in pixels, base equatorial co-ordinates, and data-reduction recipe name.

• Run with oracdr -noeng -nodisplay -from 1 -skip for efficiency.

• The $<$date$>$ comes from the header keyword DATE.

• Specification provided by Sandy Leggett.

• The text log file $ORAC_DATA_IN/$<$date$>$.nightlog, where $<$date$>$ is the UT date.
