Summary

LRIS slitmask names are currently (Fall 2011) being changed into numeric values by the slitmask acceptance system, which makes it hard for observers to identify their masks. This page describes the procedure by which the Support Astronomer can change the names assigned by the slitmask system (aka BLUNAME) into the meaningful names assigned by the observer (aka GUINAME).

Procedure

The procedure consists of a set of steps to perform in the afternoon to set the mask names to the GUINAME values that the observer wants, and steps to perform in the morning to revert the mask names to the values needed by SIAS.

Phase I

Perform these steps after instrument release to set the mask names to the values the observer wants.

Login to the LRIS host machine via
```
ssh lriseng@lrisserver
```
Run
```
consort slitname
```
and verify against SIAS
Test name conversion by
```
convert_guinames_to_blunames -D
```
If conversion looks okay, then perform conversion via
```
convert_guinames_to_blunames
```
Run
```
consort slitname
```
and check that masknames are all properly converted.
Restart any existing XLRIS to read new mask names.

Phase II

Perform these steps in the morning to revert the mask names back to the BLUNAME values required by SIAS to generate the correct LRIS configuration task for the daycrew.

Login to the LRIS host machine via
```
ssh lriseng@lrisserver
```
Test name reversion via
```
convert_blunames_to_guinames -D
```
Compare output to yesterday's SIAS to verify that the guinames are correct
Perform name reversion via
```
convert_blunames_to_guinamse
```

Phase III

If the above steps are completed after 7:00 AM HST, then the following steps are required to update the SIAS tasks.

Save the new LRIS configuration via

ssh kics@puamana /home/kics/siastng/bin/consortWrite

and check output.

Re-run Configuration Updator for LRIS from the web interface, after changing output option from paniau to mysqlserver.
Check today's SIAS and verify that the mask list is correct.
