Conditions
The following conditions are currently recognised (all are
case-insensitive):
-
"BadCel": This condition arises when reading a FrameSet from a
non-Native encoded FitsChan if an unknown celestial co-ordinate
system is specified by the CTYPE keywords.
-
"BadLat": This condition arises when reading a FrameSet from a
non-Native encoded FitsChan if the latitude of the reference point
has an absolute value greater than 90 degrees. The actual absolute
value used is set to exactly 90 degrees in these cases.
-
"NoCTYPE": This condition arises if a default CTYPE value is used
within AST_READ, due to no value being present in the supplied FitsChan.
This condition is only tested for when using non-Native encodings.
-
"NoEquinox": This condition arises if a default equinox value is used
within AST_READ, due to no value being present in the supplied FitsChan.
This condition is only tested for when using non-Native encodings.
-
"NoRadesys": This condition arises if a default reference frame is
used for an equatorial co-ordinate system within AST_READ, due to no
value being present in the supplied FitsChan. This condition is only
tested for when using non-Native encodings.
-
"NoLonpole": This condition arises if a default value is used for
the LONPOLE keyword within AST_READ, due to no value being present
in the supplied FitsChan. This condition is only tested for when
using non-Native encodings.
-
"NoLatpole": This condition arises if a default value is used for
the LATPOLE keyword within AST_READ, due to no value being present
in the supplied FitsChan. This condition is only tested for when
using non-Native encodings.
-
"NoMjd-obs": This condition arises if a default value is used for
the date of observation within AST_READ, due to no value being present
in the supplied FitsChan. This condition is only tested for when using
non-Native encodings.
-
"Tnx": This condition arises if a FrameSet is read from a FITS
header containing an IRAF "TNX" projection which includes terms
not supproted by AST. Such terms are ignored and so the resulting
FrameSet may be inaccurate.
-
"Zpx": This condition arises if a FrameSet is read from a FITS
header containing an IRAF "ZPX" projection which includes "lngcor"
or "latcor" correction terms. These terms are not supported by AST
and are ignored. The resulting FrameSet may therefore be inaccurate.
