SAMP SAMPSAMP is a messaging protocol that enables astronomy software tools to interoperate and communicate. Broadly speaking, SAMP is an abstract framework for loosely-coupled, asynchronous, RPC-like and/or event-based communication, based on a central service providing multi-directional publish/subscribe message brokering. The message semantics are extensible and use structured but weakly-typed data. For more information on SAMP, please click here.
The samp implementation for DS9 is based on the XPA model with 2 private calls:
ds9.get
Arguments
cmd (string) required
url (string) optional
Returned value
OK (samp.result map)
value (string) optional
url (string) optional
ERROR (samp.error map)
samp.errortxt (string)
ds9.set
Arguments
cmd (string) required
url (string) optional
Returned value
OK
ERROR (samp.error map)
samp.errortxt (string)
ds9.set maybe called via notification, call and call/wait. ds9.get can only be called via call and call/wait. Most of the ds9.get calls return a value string, but a few will return a url instead.
