Index files

[Abdullah Qureshi]

Hi,
Currently using wsl.

just transfered my files to RPI
resetting up my astronomy.net on the RPI 

i put the index files in /usr/share/astronomy 

but it is still not working:


---------------------------------------------------------------------
You must list at least one index in the config file (/etc/astrometry.cfg)

See http://astrometry.net/use.html about how to get some index files.

Thank you

[Dustin Lang]

What is in your /etc/astrometry.cfg file?

Is it possible you need to name the directory /usr/share/astrometry (astroMETRY not astroNOMY)?

cheers,

dustin

Can you also run solve-field, adding a "-v" (verbose) and send the full output?

thanks,

Thanks -- it looks like the index files didn't download correctly.

Make sure your web browser or whatever downloads them as binary files (not text).

I just added a "md5sums.txt" file

https://data.astrometry.net/4100/md5sums.txt

which you could use to verify your downloads.

cheers,

Thanks it works now.

I have also made a script to automatically download into the folder if interested: 
nano Index-4100.sh
chmod +x Index-4100.sh
sudo ./Index-4100.sh

#!/bin/bash

# This script downloads astrometry.net 4100-series index files (4107-4119)

# into /usr/share/astrometry. It checks whether each file already exists,

# and only downloads those that are not found.

# This script must be run as root.

if [ "$EUID" -ne 0 ]; then

    exit 1

fi

DEST="/usr/share/astrometry"

    echo "Directory $DEST does not exist. Creating it..."

    mkdir -p "$DEST"

    if [ $? -ne 0 ]; then

        echo "Failed to create $DEST. Exiting."

        exit 1

    fi

fi

BASE_URL="https://data.astrometry.net/4100"

for INDEX_NUM in {4107..4119}; do

    FILE="index-${INDEX_NUM}.fits"

    FILE_PATH="${DEST}/${FILE}"

    URL="${BASE_URL}/${FILE}"

   

    if [ -f "$FILE_PATH" ]; then

        echo "${FILE} already exists at ${DEST}; skipping download."

    else

        echo "Downloading ${FILE} from ${URL}..."

        wget -O "$FILE_PATH" "$URL"

        if [ $? -ne 0 ]; then

            echo "Error downloading ${FILE}. Exiting."
