AllWarnings - A list of all currently available condition names

Description:
This read-only attribute is a space separated list of all the conditions names recognized by the Warnings attribute. The names are listed below.

Type:
String, read-only

Class Applicability:
FitsChan
All FitsChans have this attribute.

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 astRead, 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 astRead, 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 astRead, 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 astRead, 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 astRead, 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 astRead, 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.
