Get the miscellaneous information record from an image

Synopsis
miscinfo()

Returns
Glish record or fail

Description

An AIPS++ image file can accumulate various miscellaneous information during its lifetime; it is stored in a Glish record called the miscinfo record. For example, the FITS filler puts header keywords it doesn't otherwise use into the miscinfo record. This miscinfo record is not guaranteed to have any entries, so it's up to you to check for any fields that you require.

You can also put things into this record (see setmiscinfo) yourself, to keep information that the system might not otherwise store for you.

When the image is written out to FITS, the items in the miscinfo record are written to the FITS file as keywords with the corresponding record field name.

Example

- im.miscinfo()             # print the record
[bscale=1, bzero=0, cellscal=CONSTANT] 
- header := im.miscinfo()   # capture the record for further use
