showcand
showcand
is a C-shell script which writes the most often used
information about a candidate file to standard out.
It is used to generate the
logfiles.
object - the object name
datid - the data id code
nmatch - the number of fiducial stars common to target and reference
date-obs - the Universal time date of the observation
magdiff - the magnitude difference of target to reference
mwfhm - median fwhm of target in pixels
sky - sky value in adu
skysig - the rms of the sky value in adu
dr - the row offset of the target from the reference image
dc - the column offset of the target from the reference image
Magdiffs that are negative mean that the new image is weaker than the reference.
Images with NMATCH > 1 must have used the
fiducial star method.
Images with NMATCH == 1 must have used the
correlation
method, but then one star was found to agree.
Images with NMATCH== 0 were derived bye correlation method.
Here are some examples of good images:
