Some additonal information on the content of the database (collected during analysis workshop in Zürich, unsorted, moved here from Database: RunInfo and Database: SequInfo).

General

Table functions

Sorting rows

click on the header of the column you want to sort by

Get text

save table to txt file

Print

show table without headers

Source (regexp)

• Possibility to search data of certain source(s) using regular expressions

[Row header] Sequ

Assigned sequence number, if 0: no sequence assigned.

Status

Answers whether data already arrived at the data center.

Nothing

Additional rows, for the return codes see the Error Coding page

Information on sequence basis

Status Info

[Row header] Links

cal --> html file contains log of the analysis, which is a possibility to find errors in the analysis chain.

CalInfo

Isolated inner/outer

Pixel with erroneous data where the value cannot be generated using interpolation of neighbouring pixels

MeanPedRms inner

Important entry, possibility to estimate the night sky background

Rate Unknown evts

Should not occur at all, if this rate is high the data has to be handled cautious

[Row header] Links

'star': a lot of useful information for the data checks, eg. the position of the isolated/dead pixels, or 'Rate vs. Zenith distance' (MHRate), or plot of the identified stars (MHPointing) (see wiki-page concerning data quality for details on data checks)

StarInfo

id. Stars

1. number of stars that are recognized by the starguider (also reflections...)
2. cor. Stars: number of stars that were identified by the starguider
