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.
