Fiducial Tables:
-----------------
New fiducial tables for three axies were built and compared to 
currently using ones. New fiduial tables have lower errors than current 
ones whereas new table for azimuth missed two more readings (current has
two bad readings, the new table has four). However, the current azimuth table
is three months old, and its data was collectted at temperatur of - 3 C. So
I will check in all three new tables tomorrow.

Disk Space:
-----------
  Disk space was checked and found that there are lots of room for
new data. Data for two very old mjd: 54532, 54546 were removed from the
disk.

Spectro Monthly Checkout:
-------------------------
cart 8, plate 2904 was used for the checkout.
The adjusted XMin and Xmax position are:

         b1     r1     b2     r2
XMin     3.5    2.6    3.2   12.1
XMax  2030.3 2049.0 2024.5 2056.5

The adjusted WaveMin and WaveMax are:

         b1     r1     b2     r2
WMin  3802.0 5761.3 3802.7 5799.1    
WMax  6173.4 9213.1 6171.7 9241.0

Checked and adjusted spectro focus. It's set to 9 C.

Some bias, flat, and arc images were checked. They are looked good.


PT:
----
The PT was not tested beyond bias and flats because of clouds.
The PT FF-lamp has been replaced on April 17th for the coming dark run.
  

Host2 uptime:
