Abstract:
    A catalogue of 7760 carbon stars in the Large Magellenic Cloud is
    presented. The stars were identified during a systematic survey of
    objective-prism plates taken with the UK 1.2m Schmidt Telescope. The
    catalogue is compared with other lists of carbon stars and the
    distribution of the carbon stars is discussed.

Note (1): A 4-digit photometry code
 digit 1: image area with respect to the magnitude
     0  appropriate
     1  too large in R
     2  too large in I
     3  too large in R and I
 digit 2: images that are multiple
     0  image unblended or deblended satisfactorily
     1  image deblended but with possible error
     2  image has a faint undeblended companion
     3  image has an undeblended companion
     4  image has an undeblended companion a little fainter
     5  image has an undeblended companion of equal or  brighter magnitude
     9  no information available for this code
 digit 3: multiple images that are deblended in R but not in I
     0  carbon star is fainter than the total in R by less than 0.1 mag
     1  carbon star is fainter than the total in R by 0.1-0.3 mag
     2  carbon star is fainter than the total in R by 0.3-0.5 mag
     3  carbon star is fainter than the total in R by more than 0.5 mag
     4  complex blend noted
     5  possible deblending error noted
 digit 4: indicates the SuperCOSMOS deblending parameters
     0  unblended or undeblended images in both R and I
     1  deblended images in R
     2  blended images in I
     3  deblended images in both R and I
Note (2): A 1-digit astrometry code
     1  R and I coordinates differ by more than 1 arcsec
     2  primary and secondary datasets for F56 differ by more than 1arcsec
     3  measurements were made using the cursor (e.g. no R data available)
     4  from the second F56 dataset
     5  original approximate measurements
     6  star is more than 6 deg from the plate centre
Note (3): A 1-digit spectrum code
     1  highly probably carbon
     2  probably carbon
     3  bands look weak
Note (4): A 3-digit general code to indicate possible contamination by
     b  a bright star
     g  a galaxy
     t  a satellite trail
     n  nebulosity
     c  cluster
     v  the star is likely to be a variable
        (Note that the absence of `v' does not mean that the star is not a
        variable because there are insufficient images of each star to
        determine this over the typical periods for variable carbon stars.)
Note (5): A 1-digit identification code which is
    *  when there is a nearby star, resolved by SuperCOSMOS within
       5 arcsec and no more than 1 mag fainter than the carbon star.
