COS ETCs
|
The Exposure Time Calculators (ETCs) are on-line tools
useful for predicting the signal-to-noise for various observing modes, given
specified source characteristics.

APT |
The Astronomer's Proposal Tool (APT)
is the general proposal planning tool for all HST instruments.

COS BOT Documentation (doc) |
APT Bright Object Tool (BOT) looks for bright objects in the field of view of
each observation and checks if they exceed the safety limits of an instrument. This document
provides an overview of BOT for COS observations.

Software for analyzing COS data
|
|
STSDAS
|
the IRAF package containing CALCOS, which is used to process COS data.

|
OTFR
|
"On the fly reprocessing". Requests for COS data from the
HST Archive
always return data reprocessed with the current version of CALCOS and the
best available reference files. In most cases it is easier to let the OTFR
pipeline reprocess data for you. If standard pipeline processing is inadequate,
however, CALCOS may be downloaded and run locally.
